Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472516, here are decompositions:

37 + 31472479 = 31472516
67 + 31472449 = 31472516
79 + 31472437 = 31472516
157 + 31472359 = 31472516
223 + 31472293 = 31472516
277 + 31472239 = 31472516
307 + 31472209 = 31472516
337 + 31472179 = 31472516

Showing the first eight; more decompositions exist.
