Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523184, here are decompositions:
- 23 + 31523161 = 31523184
- 41 + 31523143 = 31523184
- 53 + 31523131 = 31523184
- 71 + 31523113 = 31523184
- 73 + 31523111 = 31523184
- 103 + 31523081 = 31523184
- 131 + 31523053 = 31523184
- 157 + 31523027 = 31523184
Showing the first eight; more decompositions exist.
