Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540882, here are decompositions:

11 + 31540871 = 31540882
59 + 31540823 = 31540882
173 + 31540709 = 31540882
239 + 31540643 = 31540882
251 + 31540631 = 31540882
353 + 31540529 = 31540882
383 + 31540499 = 31540882
389 + 31540493 = 31540882

Showing the first eight; more decompositions exist.
