Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493048, here are decompositions:

19 + 31493029 = 31493048
31 + 31493017 = 31493048
127 + 31492921 = 31493048
199 + 31492849 = 31493048
211 + 31492837 = 31493048
271 + 31492777 = 31493048
277 + 31492771 = 31493048
397 + 31492651 = 31493048

Showing the first eight; more decompositions exist.
