Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626106, here are decompositions:

53 + 31626053 = 31626106
137 + 31625969 = 31626106
167 + 31625939 = 31626106
257 + 31625849 = 31626106
263 + 31625843 = 31626106
353 + 31625753 = 31626106
383 + 31625723 = 31626106
503 + 31625603 = 31626106

Showing the first eight; more decompositions exist.
