Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111742, here are decompositions:
- 11 + 111731 = 111742
- 83 + 111659 = 111742
- 89 + 111653 = 111742
- 101 + 111641 = 111742
- 131 + 111611 = 111742
- 149 + 111593 = 111742
- 233 + 111509 = 111742
- 251 + 111491 = 111742
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 111,742 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 111742 first appears in π at position 475,536 of the decimal expansion (the 475,536ordinal-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.
