Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484482, here are decompositions:

179 + 31484303 = 31484482
353 + 31484129 = 31484482
389 + 31484093 = 31484482
401 + 31484081 = 31484482
503 + 31483979 = 31484482
563 + 31483919 = 31484482
569 + 31483913 = 31484482
593 + 31483889 = 31484482

Showing the first eight; more decompositions exist.
