Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513316, here are decompositions:
- 7 + 31513309 = 31513316
- 13 + 31513303 = 31513316
- 97 + 31513219 = 31513316
- 103 + 31513213 = 31513316
- 193 + 31513123 = 31513316
- 199 + 31513117 = 31513316
- 283 + 31513033 = 31513316
- 313 + 31513003 = 31513316
Showing the first eight; more decompositions exist.
