Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492936, here are decompositions:

3 + 31492933 = 31492936
29 + 31492907 = 31492936
89 + 31492847 = 31492936
179 + 31492757 = 31492936
239 + 31492697 = 31492936
269 + 31492667 = 31492936
359 + 31492577 = 31492936
383 + 31492553 = 31492936

Showing the first eight; more decompositions exist.
