Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591634, here are decompositions:

31 + 31591603 = 31591634
37 + 31591597 = 31591634
97 + 31591537 = 31591634
157 + 31591477 = 31591634
181 + 31591453 = 31591634
457 + 31591177 = 31591634
463 + 31591171 = 31591634
541 + 31591093 = 31591634

Showing the first eight; more decompositions exist.
