Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503744, here are decompositions:
- 11 + 31503733 = 31503744
- 17 + 31503727 = 31503744
- 31 + 31503713 = 31503744
- 71 + 31503673 = 31503744
- 101 + 31503643 = 31503744
- 113 + 31503631 = 31503744
- 191 + 31503553 = 31503744
- 383 + 31503361 = 31503744
Showing the first eight; more decompositions exist.
