Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87750, here are decompositions:
- 7 + 87743 = 87750
- 11 + 87739 = 87750
- 29 + 87721 = 87750
- 31 + 87719 = 87750
- 53 + 87697 = 87750
- 59 + 87691 = 87750
- 67 + 87683 = 87750
- 71 + 87679 = 87750
Showing the first eight; more decompositions exist.
