Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448622, here are decompositions:
- 19 + 31448603 = 31448622
- 41 + 31448581 = 31448622
- 43 + 31448579 = 31448622
- 71 + 31448551 = 31448622
- 89 + 31448533 = 31448622
- 103 + 31448519 = 31448622
- 173 + 31448449 = 31448622
- 199 + 31448423 = 31448622
Showing the first eight; more decompositions exist.
