Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493302, here are decompositions:

11 + 31493291 = 31493302
53 + 31493249 = 31493302
101 + 31493201 = 31493302
131 + 31493171 = 31493302
149 + 31493153 = 31493302
233 + 31493069 = 31493302
263 + 31493039 = 31493302
293 + 31493009 = 31493302

Showing the first eight; more decompositions exist.
