Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472048, here are decompositions:
- 7 + 31472041 = 31472048
- 19 + 31472029 = 31472048
- 37 + 31472011 = 31472048
- 109 + 31471939 = 31472048
- 199 + 31471849 = 31472048
- 337 + 31471711 = 31472048
- 367 + 31471681 = 31472048
- 409 + 31471639 = 31472048
Showing the first eight; more decompositions exist.
