Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626752, here are decompositions:

43 + 31626709 = 31626752
61 + 31626691 = 31626752
163 + 31626589 = 31626752
181 + 31626571 = 31626752
271 + 31626481 = 31626752
331 + 31626421 = 31626752
523 + 31626229 = 31626752
643 + 31626109 = 31626752

Showing the first eight; more decompositions exist.
