Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535604, here are decompositions:
- 11 + 31535593 = 31535604
- 13 + 31535591 = 31535604
- 53 + 31535551 = 31535604
- 101 + 31535503 = 31535604
- 137 + 31535467 = 31535604
- 181 + 31535423 = 31535604
- 193 + 31535411 = 31535604
- 223 + 31535381 = 31535604
Showing the first eight; more decompositions exist.
