Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454032, here are decompositions:
- 41 + 31453991 = 31454032
- 89 + 31453943 = 31454032
- 101 + 31453931 = 31454032
- 149 + 31453883 = 31454032
- 191 + 31453841 = 31454032
- 353 + 31453679 = 31454032
- 461 + 31453571 = 31454032
- 503 + 31453529 = 31454032
Showing the first eight; more decompositions exist.
