Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506652, here are decompositions:

11 + 31506641 = 31506652
53 + 31506599 = 31506652
83 + 31506569 = 31506652
131 + 31506521 = 31506652
173 + 31506479 = 31506652
293 + 31506359 = 31506652
389 + 31506263 = 31506652
479 + 31506173 = 31506652

Showing the first eight; more decompositions exist.
