Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484162, here are decompositions:

19 + 31484143 = 31484162
103 + 31484059 = 31484162
181 + 31483981 = 31484162
373 + 31483789 = 31484162
439 + 31483723 = 31484162
499 + 31483663 = 31484162
613 + 31483549 = 31484162
691 + 31483471 = 31484162

Showing the first eight; more decompositions exist.
