Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493134, here are decompositions:

3 + 31493131 = 31493134
137 + 31492997 = 31493134
191 + 31492943 = 31493134
227 + 31492907 = 31493134
293 + 31492841 = 31493134
353 + 31492781 = 31493134
383 + 31492751 = 31493134
443 + 31492691 = 31493134

Showing the first eight; more decompositions exist.
