Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513046, here are decompositions:

13 + 31513033 = 31513046
43 + 31513003 = 31513046
139 + 31512907 = 31513046
223 + 31512823 = 31513046
277 + 31512769 = 31513046
307 + 31512739 = 31513046
373 + 31512673 = 31513046
547 + 31512499 = 31513046

Showing the first eight; more decompositions exist.
