Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626508, here are decompositions:

47 + 31626461 = 31626508
71 + 31626437 = 31626508
101 + 31626407 = 31626508
131 + 31626377 = 31626508
149 + 31626359 = 31626508
311 + 31626197 = 31626508
317 + 31626191 = 31626508
467 + 31626041 = 31626508

Showing the first eight; more decompositions exist.
