Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513232, here are decompositions:
- 13 + 31513219 = 31513232
- 19 + 31513213 = 31513232
- 31 + 31513201 = 31513232
- 109 + 31513123 = 31513232
- 199 + 31513033 = 31513232
- 229 + 31513003 = 31513232
- 241 + 31512991 = 31513232
- 409 + 31512823 = 31513232
Showing the first eight; more decompositions exist.
