Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539748, here are decompositions:
- 11 + 31539737 = 31539748
- 41 + 31539707 = 31539748
- 89 + 31539659 = 31539748
- 179 + 31539569 = 31539748
- 281 + 31539467 = 31539748
- 347 + 31539401 = 31539748
- 419 + 31539329 = 31539748
- 557 + 31539191 = 31539748
Showing the first eight; more decompositions exist.
