Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527964, here are decompositions:
- 23 + 31527941 = 31527964
- 137 + 31527827 = 31527964
- 263 + 31527701 = 31527964
- 431 + 31527533 = 31527964
- 443 + 31527521 = 31527964
- 467 + 31527497 = 31527964
- 557 + 31527407 = 31527964
- 641 + 31527323 = 31527964
Showing the first eight; more decompositions exist.
