Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103742, here are decompositions:
- 19 + 103723 = 103742
- 43 + 103699 = 103742
- 61 + 103681 = 103742
- 73 + 103669 = 103742
- 151 + 103591 = 103742
- 181 + 103561 = 103742
- 193 + 103549 = 103742
- 271 + 103471 = 103742
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 103,742 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 103742 first appears in π at position 489,969 of the decimal expansion (the 489,969ordinal-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.
