Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493074, here are decompositions:

5 + 31493069 = 31493074
17 + 31493057 = 31493074
83 + 31492991 = 31493074
131 + 31492943 = 31493074
167 + 31492907 = 31493074
227 + 31492847 = 31493074
233 + 31492841 = 31493074
293 + 31492781 = 31493074

Showing the first eight; more decompositions exist.
