Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474514, here are decompositions:

13 + 31474501 = 31474514
151 + 31474363 = 31474514
157 + 31474357 = 31474514
163 + 31474351 = 31474514
223 + 31474291 = 31474514
373 + 31474141 = 31474514
457 + 31474057 = 31474514
523 + 31473991 = 31474514

Showing the first eight; more decompositions exist.
