Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484708, here are decompositions:

61 + 31484647 = 31484708
139 + 31484569 = 31484708
331 + 31484377 = 31484708
349 + 31484359 = 31484708
499 + 31484209 = 31484708
547 + 31484161 = 31484708
727 + 31483981 = 31484708
751 + 31483957 = 31484708

Showing the first eight; more decompositions exist.
