Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545924, here are decompositions:
- 5 + 31545919 = 31545924
- 23 + 31545901 = 31545924
- 37 + 31545887 = 31545924
- 83 + 31545841 = 31545924
- 181 + 31545743 = 31545924
- 211 + 31545713 = 31545924
- 257 + 31545667 = 31545924
- 283 + 31545641 = 31545924
Showing the first eight; more decompositions exist.
