Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738100, here are decompositions:
- 11 + 8738089 = 8738100
- 13 + 8738087 = 8738100
- 17 + 8738083 = 8738100
- 29 + 8738071 = 8738100
- 47 + 8738053 = 8738100
- 53 + 8738047 = 8738100
- 67 + 8738033 = 8738100
- 89 + 8738011 = 8738100
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 8,738,100 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
