Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473600, here are decompositions:
- 7 + 31473593 = 31473600
- 17 + 31473583 = 31473600
- 19 + 31473581 = 31473600
- 71 + 31473529 = 31473600
- 113 + 31473487 = 31473600
- 163 + 31473437 = 31473600
- 241 + 31473359 = 31473600
- 269 + 31473331 = 31473600
Showing the first eight; more decompositions exist.
