Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539776, here are decompositions:
- 13 + 31539763 = 31539776
- 19 + 31539757 = 31539776
- 127 + 31539649 = 31539776
- 193 + 31539583 = 31539776
- 277 + 31539499 = 31539776
- 337 + 31539439 = 31539776
- 409 + 31539367 = 31539776
- 439 + 31539337 = 31539776
Showing the first eight; more decompositions exist.
