Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618022, here are decompositions:
- 19 + 31618003 = 31618022
- 61 + 31617961 = 31618022
- 151 + 31617871 = 31618022
- 211 + 31617811 = 31618022
- 349 + 31617673 = 31618022
- 439 + 31617583 = 31618022
- 463 + 31617559 = 31618022
- 613 + 31617409 = 31618022
Showing the first eight; more decompositions exist.
