Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493254, here are decompositions:

3 + 31493251 = 31493254
5 + 31493249 = 31493254
53 + 31493201 = 31493254
83 + 31493171 = 31493254
101 + 31493153 = 31493254
197 + 31493057 = 31493254
257 + 31492997 = 31493254
263 + 31492991 = 31493254

Showing the first eight; more decompositions exist.
