Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523340, here are decompositions:
- 11 + 31523329 = 31523340
- 31 + 31523309 = 31523340
- 47 + 31523293 = 31523340
- 61 + 31523279 = 31523340
- 73 + 31523267 = 31523340
- 89 + 31523251 = 31523340
- 97 + 31523243 = 31523340
- 103 + 31523237 = 31523340
Showing the first eight; more decompositions exist.
