Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539952, here are decompositions:
- 89 + 31539863 = 31539952
- 113 + 31539839 = 31539952
- 131 + 31539821 = 31539952
- 239 + 31539713 = 31539952
- 281 + 31539671 = 31539952
- 293 + 31539659 = 31539952
- 359 + 31539593 = 31539952
- 383 + 31539569 = 31539952
Showing the first eight; more decompositions exist.
