Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516652, here are decompositions:

19 + 31516633 = 31516652
109 + 31516543 = 31516652
151 + 31516501 = 31516652
229 + 31516423 = 31516652
241 + 31516411 = 31516652
463 + 31516189 = 31516652
499 + 31516153 = 31516652
523 + 31516129 = 31516652

Showing the first eight; more decompositions exist.
