Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539568, here are decompositions:
- 101 + 31539467 = 31539568
- 167 + 31539401 = 31539568
- 191 + 31539377 = 31539568
- 239 + 31539329 = 31539568
- 479 + 31539089 = 31539568
- 521 + 31539047 = 31539568
- 617 + 31538951 = 31539568
- 761 + 31538807 = 31539568
Showing the first eight; more decompositions exist.
