Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518696, here are decompositions:

5 + 31518691 = 31518696
19 + 31518677 = 31518696
23 + 31518673 = 31518696
37 + 31518659 = 31518696
43 + 31518653 = 31518696
89 + 31518607 = 31518696
103 + 31518593 = 31518696
107 + 31518589 = 31518696

Showing the first eight; more decompositions exist.
