Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449424, here are decompositions:
- 3 + 31449421 = 31449424
- 23 + 31449401 = 31449424
- 47 + 31449377 = 31449424
- 101 + 31449323 = 31449424
- 137 + 31449287 = 31449424
- 191 + 31449233 = 31449424
- 233 + 31449191 = 31449424
- 353 + 31449071 = 31449424
Showing the first eight; more decompositions exist.
