Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571446, here are decompositions:

47 + 31571399 = 31571446
113 + 31571333 = 31571446
227 + 31571219 = 31571446
233 + 31571213 = 31571446
239 + 31571207 = 31571446
383 + 31571063 = 31571446
449 + 31570997 = 31571446
587 + 31570859 = 31571446

Showing the first eight; more decompositions exist.
