Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545934, here are decompositions:
- 11 + 31545923 = 31545934
- 47 + 31545887 = 31545934
- 191 + 31545743 = 31545934
- 197 + 31545737 = 31545934
- 293 + 31545641 = 31545934
- 311 + 31545623 = 31545934
- 617 + 31545317 = 31545934
- 647 + 31545287 = 31545934
Showing the first eight; more decompositions exist.
