Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572914, here are decompositions:

13 + 31572901 = 31572914
73 + 31572841 = 31572914
151 + 31572763 = 31572914
181 + 31572733 = 31572914
277 + 31572637 = 31572914
613 + 31572301 = 31572914
631 + 31572283 = 31572914
661 + 31572253 = 31572914

Showing the first eight; more decompositions exist.
