Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523904, here are decompositions:
- 23 + 31523881 = 31523904
- 53 + 31523851 = 31523904
- 101 + 31523803 = 31523904
- 103 + 31523801 = 31523904
- 151 + 31523753 = 31523904
- 197 + 31523707 = 31523904
- 257 + 31523647 = 31523904
- 271 + 31523633 = 31523904
Showing the first eight; more decompositions exist.
