Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626792, here are decompositions:

5 + 31626787 = 31626792
83 + 31626709 = 31626792
101 + 31626691 = 31626792
103 + 31626689 = 31626792
173 + 31626619 = 31626792
229 + 31626563 = 31626792
293 + 31626499 = 31626792
311 + 31626481 = 31626792

Showing the first eight; more decompositions exist.
