Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450254, here are decompositions:

7 + 31450247 = 31450254
37 + 31450217 = 31450254
47 + 31450207 = 31450254
113 + 31450141 = 31450254
137 + 31450117 = 31450254
151 + 31450103 = 31450254
193 + 31450061 = 31450254
197 + 31450057 = 31450254

Showing the first eight; more decompositions exist.
