Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626316, here are decompositions:

83 + 31626233 = 31626316
107 + 31626209 = 31626316
149 + 31626167 = 31626316
263 + 31626053 = 31626316
347 + 31625969 = 31626316
353 + 31625963 = 31626316
467 + 31625849 = 31626316
509 + 31625807 = 31626316

Showing the first eight; more decompositions exist.
