Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87566, here are decompositions:
- 7 + 87559 = 87566
- 13 + 87553 = 87566
- 19 + 87547 = 87566
- 43 + 87523 = 87566
- 139 + 87427 = 87566
- 163 + 87403 = 87566
- 229 + 87337 = 87566
- 313 + 87253 = 87566
Showing the first eight; more decompositions exist.
