Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040842, here are decompositions:
- 29 + 1040813 = 1040842
- 59 + 1040783 = 1040842
- 71 + 1040771 = 1040842
- 191 + 1040651 = 1040842
- 263 + 1040579 = 1040842
- 311 + 1040531 = 1040842
- 353 + 1040489 = 1040842
- 359 + 1040483 = 1040842
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 1,040,842 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
