Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513416, here are decompositions:
- 5 + 31513411 = 31513416
- 13 + 31513403 = 31513416
- 43 + 31513373 = 31513416
- 83 + 31513333 = 31513416
- 107 + 31513309 = 31513416
- 113 + 31513303 = 31513416
- 157 + 31513259 = 31513416
- 197 + 31513219 = 31513416
Showing the first eight; more decompositions exist.
