Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493322, here are decompositions:

31 + 31493291 = 31493322
71 + 31493251 = 31493322
73 + 31493249 = 31493322
131 + 31493191 = 31493322
151 + 31493171 = 31493322
191 + 31493131 = 31493322
239 + 31493083 = 31493322
269 + 31493053 = 31493322

Showing the first eight; more decompositions exist.
