Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448708, here are decompositions:
- 61 + 31448647 = 31448708
- 127 + 31448581 = 31448708
- 157 + 31448551 = 31448708
- 229 + 31448479 = 31448708
- 331 + 31448377 = 31448708
- 409 + 31448299 = 31448708
- 547 + 31448161 = 31448708
- 691 + 31448017 = 31448708
Showing the first eight; more decompositions exist.
