Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493276, here are decompositions:

193 + 31493083 = 31493276
223 + 31493053 = 31493276
229 + 31493047 = 31493276
313 + 31492963 = 31493276
439 + 31492837 = 31493276
499 + 31492777 = 31493276
613 + 31492663 = 31493276
673 + 31492603 = 31493276

Showing the first eight; more decompositions exist.
