Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020240, here are decompositions:
- 7 + 1020233 = 1020240
- 17 + 1020223 = 1020240
- 83 + 1020157 = 1020240
- 97 + 1020143 = 1020240
- 103 + 1020137 = 1020240
- 127 + 1020113 = 1020240
- 131 + 1020109 = 1020240
- 139 + 1020101 = 1020240
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 1,020,240 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
