Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513036, here are decompositions:

3 + 31513033 = 31513036
29 + 31513007 = 31513036
89 + 31512947 = 31513036
167 + 31512869 = 31513036
197 + 31512839 = 31513036
257 + 31512779 = 31513036
353 + 31512683 = 31513036
419 + 31512617 = 31513036

Showing the first eight; more decompositions exist.
