Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613762, here are decompositions:

43 + 31613719 = 31613762
139 + 31613623 = 31613762
181 + 31613581 = 31613762
211 + 31613551 = 31613762
223 + 31613539 = 31613762
379 + 31613383 = 31613762
421 + 31613341 = 31613762
571 + 31613191 = 31613762

Showing the first eight; more decompositions exist.
