Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622626, here are decompositions:
- 47 + 31622579 = 31622626
- 89 + 31622537 = 31622626
- 107 + 31622519 = 31622626
- 197 + 31622429 = 31622626
- 257 + 31622369 = 31622626
- 353 + 31622273 = 31622626
- 389 + 31622237 = 31622626
- 419 + 31622207 = 31622626
Showing the first eight; more decompositions exist.
