Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626458, here are decompositions:

37 + 31626421 = 31626458
211 + 31626247 = 31626458
229 + 31626229 = 31626458
349 + 31626109 = 31626458
379 + 31626079 = 31626458
439 + 31626019 = 31626458
541 + 31625917 = 31626458
547 + 31625911 = 31626458

Showing the first eight; more decompositions exist.
