Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545008, here are decompositions:
- 7 + 31545001 = 31545008
- 67 + 31544941 = 31545008
- 109 + 31544899 = 31545008
- 151 + 31544857 = 31545008
- 181 + 31544827 = 31545008
- 421 + 31544587 = 31545008
- 457 + 31544551 = 31545008
- 499 + 31544509 = 31545008
Showing the first eight; more decompositions exist.
