Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474832, here are decompositions:
- 3 + 31474829 = 31474832
- 31 + 31474801 = 31474832
- 139 + 31474693 = 31474832
- 163 + 31474669 = 31474832
- 283 + 31474549 = 31474832
- 313 + 31474519 = 31474832
- 331 + 31474501 = 31474832
- 409 + 31474423 = 31474832
Showing the first eight; more decompositions exist.
