Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539704, here are decompositions:
- 43 + 31539661 = 31539704
- 61 + 31539643 = 31539704
- 181 + 31539523 = 31539704
- 283 + 31539421 = 31539704
- 337 + 31539367 = 31539704
- 367 + 31539337 = 31539704
- 373 + 31539331 = 31539704
- 421 + 31539283 = 31539704
Showing the first eight; more decompositions exist.
