Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538326, here are decompositions:

173 + 31538153 = 31538326
263 + 31538063 = 31538326
293 + 31538033 = 31538326
467 + 31537859 = 31538326
503 + 31537823 = 31538326
857 + 31537469 = 31538326
1013 + 31537313 = 31538326
1019 + 31537307 = 31538326

Showing the first eight; more decompositions exist.
