Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492004, here are decompositions:

163 + 31491841 = 31492004
211 + 31491793 = 31492004
277 + 31491727 = 31492004
307 + 31491697 = 31492004
367 + 31491637 = 31492004
433 + 31491571 = 31492004
457 + 31491547 = 31492004
673 + 31491331 = 31492004

Showing the first eight; more decompositions exist.
