Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501242, here are decompositions:
- 13 + 501229 = 501242
- 19 + 501223 = 501242
- 103 + 501139 = 501242
- 109 + 501133 = 501242
- 139 + 501103 = 501242
- 199 + 501043 = 501242
- 211 + 501031 = 501242
- 223 + 501019 = 501242
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 501,242 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
