Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531826, here are decompositions:

13 + 31531813 = 31531826
199 + 31531627 = 31531826
373 + 31531453 = 31531826
409 + 31531417 = 31531826
457 + 31531369 = 31531826
523 + 31531303 = 31531826
577 + 31531249 = 31531826
709 + 31531117 = 31531826

Showing the first eight; more decompositions exist.
