Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492834, here are decompositions:

53 + 31492781 = 31492834
83 + 31492751 = 31492834
137 + 31492697 = 31492834
167 + 31492667 = 31492834
257 + 31492577 = 31492834
281 + 31492553 = 31492834
293 + 31492541 = 31492834
431 + 31492403 = 31492834

Showing the first eight; more decompositions exist.
