Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535616, here are decompositions:
- 23 + 31535593 = 31535616
- 67 + 31535549 = 31535616
- 113 + 31535503 = 31535616
- 149 + 31535467 = 31535616
- 193 + 31535423 = 31535616
- 197 + 31535419 = 31535616
- 199 + 31535417 = 31535616
- 239 + 31535377 = 31535616
Showing the first eight; more decompositions exist.
