Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626702, here are decompositions:

11 + 31626691 = 31626702
13 + 31626689 = 31626702
83 + 31626619 = 31626702
113 + 31626589 = 31626702
131 + 31626571 = 31626702
139 + 31626563 = 31626702
241 + 31626461 = 31626702
281 + 31626421 = 31626702

Showing the first eight; more decompositions exist.
