Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758240, here are decompositions:
- 11 + 8758229 = 8758240
- 41 + 8758199 = 8758240
- 53 + 8758187 = 8758240
- 83 + 8758157 = 8758240
- 137 + 8758103 = 8758240
- 173 + 8758067 = 8758240
- 191 + 8758049 = 8758240
- 233 + 8758007 = 8758240
Showing the first eight; more decompositions exist.
