Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11690, here are decompositions:
- 13 + 11677 = 11690
- 73 + 11617 = 11690
- 97 + 11593 = 11690
- 103 + 11587 = 11690
- 139 + 11551 = 11690
- 163 + 11527 = 11690
- 193 + 11497 = 11690
- 199 + 11491 = 11690
Showing the first eight; more decompositions exist.
