Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009742, here are decompositions:
- 73 + 1009669 = 1009742
- 211 + 1009531 = 1009742
- 241 + 1009501 = 1009742
- 373 + 1009369 = 1009742
- 421 + 1009321 = 1009742
- 439 + 1009303 = 1009742
- 499 + 1009243 = 1009742
- 541 + 1009201 = 1009742
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,009,742 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 1009742 first appears in π at position 135,760 of the decimal expansion (the 135,760ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
