Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483274, here are decompositions:

13 + 31483261 = 31483274
37 + 31483237 = 31483274
61 + 31483213 = 31483274
157 + 31483117 = 31483274
181 + 31483093 = 31483274
223 + 31483051 = 31483274
271 + 31483003 = 31483274
283 + 31482991 = 31483274

Showing the first eight; more decompositions exist.
