Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484528, here are decompositions:

67 + 31484461 = 31484528
79 + 31484449 = 31484528
151 + 31484377 = 31484528
211 + 31484317 = 31484528
349 + 31484179 = 31484528
367 + 31484161 = 31484528
457 + 31484071 = 31484528
547 + 31483981 = 31484528

Showing the first eight; more decompositions exist.
