Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518652, here are decompositions:

5 + 31518647 = 31518652
59 + 31518593 = 31518652
131 + 31518521 = 31518652
443 + 31518209 = 31518652
479 + 31518173 = 31518652
563 + 31518089 = 31518652
653 + 31517999 = 31518652
701 + 31517951 = 31518652

Showing the first eight; more decompositions exist.
