Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539984, here are decompositions:
- 13 + 31539971 = 31539984
- 17 + 31539967 = 31539984
- 53 + 31539931 = 31539984
- 83 + 31539901 = 31539984
- 127 + 31539857 = 31539984
- 163 + 31539821 = 31539984
- 167 + 31539817 = 31539984
- 227 + 31539757 = 31539984
Showing the first eight; more decompositions exist.
