Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539012, here are decompositions:
- 5 + 31539007 = 31539012
- 61 + 31538951 = 31539012
- 223 + 31538789 = 31539012
- 233 + 31538779 = 31539012
- 269 + 31538743 = 31539012
- 283 + 31538729 = 31539012
- 293 + 31538719 = 31539012
- 359 + 31538653 = 31539012
Showing the first eight; more decompositions exist.
