Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492996, here are decompositions:

5 + 31492991 = 31492996
53 + 31492943 = 31492996
89 + 31492907 = 31492996
137 + 31492859 = 31492996
149 + 31492847 = 31492996
239 + 31492757 = 31492996
419 + 31492577 = 31492996
443 + 31492553 = 31492996

Showing the first eight; more decompositions exist.
