Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557684, here are decompositions:
- 7 + 31557677 = 31557684
- 13 + 31557671 = 31557684
- 47 + 31557637 = 31557684
- 73 + 31557611 = 31557684
- 83 + 31557601 = 31557684
- 131 + 31557553 = 31557684
- 173 + 31557511 = 31557684
- 181 + 31557503 = 31557684
Showing the first eight; more decompositions exist.
