Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513682, here are decompositions:

61 + 31513621 = 31513682
103 + 31513579 = 31513682
271 + 31513411 = 31513682
349 + 31513333 = 31513682
373 + 31513309 = 31513682
379 + 31513303 = 31513682
463 + 31513219 = 31513682
619 + 31513063 = 31513682

Showing the first eight; more decompositions exist.
