Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024642, here are decompositions:
- 53 + 1024589 = 1024642
- 83 + 1024559 = 1024642
- 131 + 1024511 = 1024642
- 251 + 1024391 = 1024642
- 263 + 1024379 = 1024642
- 491 + 1024151 = 1024642
- 569 + 1024073 = 1024642
- 701 + 1023941 = 1024642
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 1,024,642 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
