Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87756, here are decompositions:
- 5 + 87751 = 87756
- 13 + 87743 = 87756
- 17 + 87739 = 87756
- 37 + 87719 = 87756
- 59 + 87697 = 87756
- 73 + 87683 = 87756
- 107 + 87649 = 87756
- 113 + 87643 = 87756
Showing the first eight; more decompositions exist.
