Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627466, here are decompositions:

109 + 31627357 = 31627466
163 + 31627303 = 31627466
223 + 31627243 = 31627466
229 + 31627237 = 31627466
397 + 31627069 = 31627466
433 + 31627033 = 31627466
439 + 31627027 = 31627466
487 + 31626979 = 31627466

Showing the first eight; more decompositions exist.
