Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486804, here are decompositions:

53 + 31486751 = 31486804
71 + 31486733 = 31486804
191 + 31486613 = 31486804
233 + 31486571 = 31486804
311 + 31486493 = 31486804
347 + 31486457 = 31486804
353 + 31486451 = 31486804
467 + 31486337 = 31486804

Showing the first eight; more decompositions exist.
