Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555670, here are decompositions:
- 7 + 31555663 = 31555670
- 19 + 31555651 = 31555670
- 37 + 31555633 = 31555670
- 67 + 31555603 = 31555670
- 127 + 31555543 = 31555670
- 241 + 31555429 = 31555670
- 283 + 31555387 = 31555670
- 373 + 31555297 = 31555670
Showing the first eight; more decompositions exist.
