Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626608, here are decompositions:

19 + 31626589 = 31626608
37 + 31626571 = 31626608
61 + 31626547 = 31626608
109 + 31626499 = 31626608
127 + 31626481 = 31626608
241 + 31626367 = 31626608
271 + 31626337 = 31626608
379 + 31626229 = 31626608

Showing the first eight; more decompositions exist.
