Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626764, here are decompositions:

73 + 31626691 = 31626764
97 + 31626667 = 31626764
157 + 31626607 = 31626764
193 + 31626571 = 31626764
271 + 31626493 = 31626764
283 + 31626481 = 31626764
397 + 31626367 = 31626764
571 + 31626193 = 31626764

Showing the first eight; more decompositions exist.
