Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539716, here are decompositions:
- 3 + 31539713 = 31539716
- 67 + 31539649 = 31539716
- 73 + 31539643 = 31539716
- 193 + 31539523 = 31539716
- 277 + 31539439 = 31539716
- 349 + 31539367 = 31539716
- 367 + 31539349 = 31539716
- 379 + 31539337 = 31539716
Showing the first eight; more decompositions exist.
