Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527962, here are decompositions:

31 + 31527931 = 31527962
181 + 31527781 = 31527962
379 + 31527583 = 31527962
421 + 31527541 = 31527962
439 + 31527523 = 31527962
463 + 31527499 = 31527962
619 + 31527343 = 31527962
709 + 31527253 = 31527962

Showing the first eight; more decompositions exist.
