Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572626, here are decompositions:

37 + 31572589 = 31572626
67 + 31572559 = 31572626
97 + 31572529 = 31572626
103 + 31572523 = 31572626
223 + 31572403 = 31572626
373 + 31572253 = 31572626
577 + 31572049 = 31572626
619 + 31572007 = 31572626

Showing the first eight; more decompositions exist.
