Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626184, here are decompositions:

17 + 31626167 = 31626184
53 + 31626131 = 31626184
131 + 31626053 = 31626184
173 + 31626011 = 31626184
197 + 31625987 = 31626184
431 + 31625753 = 31626184
461 + 31625723 = 31626184
503 + 31625681 = 31626184

Showing the first eight; more decompositions exist.
