Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494260, here are decompositions:

3 + 31494257 = 31494260
13 + 31494247 = 31494260
19 + 31494241 = 31494260
103 + 31494157 = 31494260
163 + 31494097 = 31494260
181 + 31494079 = 31494260
271 + 31493989 = 31494260
277 + 31493983 = 31494260

Showing the first eight; more decompositions exist.
