Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460294, here are decompositions:

3 + 31460291 = 31460294
13 + 31460281 = 31460294
31 + 31460263 = 31460294
97 + 31460197 = 31460294
127 + 31460167 = 31460294
157 + 31460137 = 31460294
241 + 31460053 = 31460294
277 + 31460017 = 31460294

Showing the first eight; more decompositions exist.
