Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492708, here are decompositions:

11 + 31492697 = 31492708
17 + 31492691 = 31492708
41 + 31492667 = 31492708
131 + 31492577 = 31492708
167 + 31492541 = 31492708
179 + 31492529 = 31492708
389 + 31492319 = 31492708
431 + 31492277 = 31492708

Showing the first eight; more decompositions exist.
