Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449370, here are decompositions:
- 11 + 31449359 = 31449370
- 47 + 31449323 = 31449370
- 83 + 31449287 = 31449370
- 107 + 31449263 = 31449370
- 137 + 31449233 = 31449370
- 179 + 31449191 = 31449370
- 191 + 31449179 = 31449370
- 317 + 31449053 = 31449370
Showing the first eight; more decompositions exist.
