Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160842, here are decompositions:
- 13 + 160829 = 160842
- 29 + 160813 = 160842
- 53 + 160789 = 160842
- 61 + 160781 = 160842
- 89 + 160753 = 160842
- 103 + 160739 = 160842
- 131 + 160711 = 160842
- 173 + 160669 = 160842
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 160,842 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 160842 first appears in π at position 3,860 of the decimal expansion (the 3,860ordinal-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.
