Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527864, here are decompositions:
- 37 + 31527827 = 31527864
- 47 + 31527817 = 31527864
- 83 + 31527781 = 31527864
- 163 + 31527701 = 31527864
- 167 + 31527697 = 31527864
- 281 + 31527583 = 31527864
- 331 + 31527533 = 31527864
- 367 + 31527497 = 31527864
Showing the first eight; more decompositions exist.
