Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938742, here are decompositions:
- 29 + 938713 = 938742
- 61 + 938681 = 938742
- 83 + 938659 = 938742
- 131 + 938611 = 938742
- 151 + 938591 = 938742
- 173 + 938569 = 938742
- 179 + 938563 = 938742
- 251 + 938491 = 938742
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 938,742 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 938742 first appears in π at position 203,604 of the decimal expansion (the 203,604ordinal-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.
