Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494254, here are decompositions:

7 + 31494247 = 31494254
13 + 31494241 = 31494254
97 + 31494157 = 31494254
157 + 31494097 = 31494254
163 + 31494091 = 31494254
271 + 31493983 = 31494254
313 + 31493941 = 31494254
373 + 31493881 = 31494254

Showing the first eight; more decompositions exist.
