Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8124, here are decompositions:
- 7 + 8117 = 8124
- 13 + 8111 = 8124
- 23 + 8101 = 8124
- 31 + 8093 = 8124
- 37 + 8087 = 8124
- 43 + 8081 = 8124
- 71 + 8053 = 8124
- 107 + 8017 = 8124
Showing the first eight; more decompositions exist.
