Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474938, here are decompositions:
- 7 + 31474931 = 31474938
- 71 + 31474867 = 31474938
- 109 + 31474829 = 31474938
- 137 + 31474801 = 31474938
- 191 + 31474747 = 31474938
- 251 + 31474687 = 31474938
- 269 + 31474669 = 31474938
- 337 + 31474601 = 31474938
Showing the first eight; more decompositions exist.
