Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527958, here are decompositions:
- 17 + 31527941 = 31527958
- 71 + 31527887 = 31527958
- 131 + 31527827 = 31527958
- 257 + 31527701 = 31527958
- 269 + 31527689 = 31527958
- 281 + 31527677 = 31527958
- 389 + 31527569 = 31527958
- 461 + 31527497 = 31527958
Showing the first eight; more decompositions exist.
