Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484732, here are decompositions:

163 + 31484569 = 31484732
199 + 31484533 = 31484732
229 + 31484503 = 31484732
271 + 31484461 = 31484732
283 + 31484449 = 31484732
373 + 31484359 = 31484732
379 + 31484353 = 31484732
523 + 31484209 = 31484732

Showing the first eight; more decompositions exist.
