Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537882, here are decompositions:

11 + 31537871 = 31537882
23 + 31537859 = 31537882
59 + 31537823 = 31537882
191 + 31537691 = 31537882
251 + 31537631 = 31537882
401 + 31537481 = 31537882
449 + 31537433 = 31537882
491 + 31537391 = 31537882

Showing the first eight; more decompositions exist.
