Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15788, here are decompositions:
- 61 + 15727 = 15788
- 109 + 15679 = 15788
- 127 + 15661 = 15788
- 139 + 15649 = 15788
- 181 + 15607 = 15788
- 229 + 15559 = 15788
- 277 + 15511 = 15788
- 337 + 15451 = 15788
Showing the first eight; more decompositions exist.
