Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484012, here are decompositions:

31 + 31483981 = 31484012
151 + 31483861 = 31484012
193 + 31483819 = 31484012
211 + 31483801 = 31484012
223 + 31483789 = 31484012
349 + 31483663 = 31484012
463 + 31483549 = 31484012
541 + 31483471 = 31484012

Showing the first eight; more decompositions exist.
