Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539794, here are decompositions:
- 31 + 31539763 = 31539794
- 37 + 31539757 = 31539794
- 67 + 31539727 = 31539794
- 151 + 31539643 = 31539794
- 211 + 31539583 = 31539794
- 271 + 31539523 = 31539794
- 373 + 31539421 = 31539794
- 457 + 31539337 = 31539794
Showing the first eight; more decompositions exist.
