Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571674, here are decompositions:

23 + 31571651 = 31571674
47 + 31571627 = 31571674
53 + 31571621 = 31571674
83 + 31571591 = 31571674
227 + 31571447 = 31571674
293 + 31571381 = 31571674
347 + 31571327 = 31571674
461 + 31571213 = 31571674

Showing the first eight; more decompositions exist.
