Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15650, here are decompositions:
- 3 + 15647 = 15650
- 7 + 15643 = 15650
- 31 + 15619 = 15650
- 43 + 15607 = 15650
- 67 + 15583 = 15650
- 109 + 15541 = 15650
- 139 + 15511 = 15650
- 157 + 15493 = 15650
Showing the first eight; more decompositions exist.
