Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493292, here are decompositions:

41 + 31493251 = 31493292
43 + 31493249 = 31493292
101 + 31493191 = 31493292
139 + 31493153 = 31493292
223 + 31493069 = 31493292
239 + 31493053 = 31493292
263 + 31493029 = 31493292
283 + 31493009 = 31493292

Showing the first eight; more decompositions exist.
