Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15692, here are decompositions:
- 13 + 15679 = 15692
- 31 + 15661 = 15692
- 43 + 15649 = 15692
- 73 + 15619 = 15692
- 109 + 15583 = 15692
- 151 + 15541 = 15692
- 181 + 15511 = 15692
- 199 + 15493 = 15692
Showing the first eight; more decompositions exist.
