Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493274, here are decompositions:

23 + 31493251 = 31493274
73 + 31493201 = 31493274
83 + 31493191 = 31493274
103 + 31493171 = 31493274
191 + 31493083 = 31493274
227 + 31493047 = 31493274
257 + 31493017 = 31493274
277 + 31492997 = 31493274

Showing the first eight; more decompositions exist.
