Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566626, here are decompositions:

37 + 31566589 = 31566626
67 + 31566559 = 31566626
79 + 31566547 = 31566626
103 + 31566523 = 31566626
109 + 31566517 = 31566626
139 + 31566487 = 31566626
199 + 31566427 = 31566626
229 + 31566397 = 31566626

Showing the first eight; more decompositions exist.
