Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535590, here are decompositions:
- 41 + 31535549 = 31535590
- 167 + 31535423 = 31535590
- 173 + 31535417 = 31535590
- 179 + 31535411 = 31535590
- 263 + 31535327 = 31535590
- 269 + 31535321 = 31535590
- 419 + 31535171 = 31535590
- 467 + 31535123 = 31535590
Showing the first eight; more decompositions exist.
