Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523040, here are decompositions:
- 13 + 31523027 = 31523040
- 19 + 31523021 = 31523040
- 37 + 31523003 = 31523040
- 53 + 31522987 = 31523040
- 61 + 31522979 = 31523040
- 79 + 31522961 = 31523040
- 89 + 31522951 = 31523040
- 103 + 31522937 = 31523040
Showing the first eight; more decompositions exist.
