Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449224, here are decompositions:
- 61 + 31449163 = 31449224
- 97 + 31449127 = 31449224
- 181 + 31449043 = 31449224
- 421 + 31448803 = 31449224
- 577 + 31448647 = 31449224
- 643 + 31448581 = 31449224
- 673 + 31448551 = 31449224
- 691 + 31448533 = 31449224
Showing the first eight; more decompositions exist.
