Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160742, here are decompositions:
- 3 + 160739 = 160742
- 19 + 160723 = 160742
- 31 + 160711 = 160742
- 61 + 160681 = 160742
- 73 + 160669 = 160742
- 79 + 160663 = 160742
- 103 + 160639 = 160742
- 139 + 160603 = 160742
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 160,742 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 160742 first appears in π at position 162,114 of the decimal expansion (the 162,114ordinal-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.
