Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523688, here are decompositions:
- 19 + 31523669 = 31523688
- 29 + 31523659 = 31523688
- 37 + 31523651 = 31523688
- 41 + 31523647 = 31523688
- 89 + 31523599 = 31523688
- 109 + 31523579 = 31523688
- 149 + 31523539 = 31523688
- 151 + 31523537 = 31523688
Showing the first eight; more decompositions exist.
