Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738520, here are decompositions:
- 13 + 8738507 = 8738520
- 29 + 8738491 = 8738520
- 47 + 8738473 = 8738520
- 71 + 8738449 = 8738520
- 73 + 8738447 = 8738520
- 83 + 8738437 = 8738520
- 113 + 8738407 = 8738520
- 137 + 8738383 = 8738520
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 8,738,520 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
