Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159242, here are decompositions:
- 19 + 159223 = 159242
- 43 + 159199 = 159242
- 73 + 159169 = 159242
- 163 + 159079 = 159242
- 229 + 159013 = 159242
- 283 + 158959 = 159242
- 379 + 158863 = 159242
- 439 + 158803 = 159242
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 159,242 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
