Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87752, here are decompositions:
- 13 + 87739 = 87752
- 31 + 87721 = 87752
- 61 + 87691 = 87752
- 73 + 87679 = 87752
- 103 + 87649 = 87752
- 109 + 87643 = 87752
- 139 + 87613 = 87752
- 163 + 87589 = 87752
Showing the first eight; more decompositions exist.
