Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013872, here are decompositions:
- 29 + 1013843 = 1013872
- 53 + 1013819 = 1013872
- 59 + 1013813 = 1013872
- 131 + 1013741 = 1013872
- 173 + 1013699 = 1013872
- 191 + 1013681 = 1013872
- 263 + 1013609 = 1013872
- 269 + 1013603 = 1013872
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 1,013,872 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
