Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463804, here are decompositions:

7 + 31463797 = 31463804
37 + 31463767 = 31463804
61 + 31463743 = 31463804
271 + 31463533 = 31463804
277 + 31463527 = 31463804
397 + 31463407 = 31463804
487 + 31463317 = 31463804
523 + 31463281 = 31463804

Showing the first eight; more decompositions exist.
