Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559514, here are decompositions:

13 + 31559501 = 31559514
43 + 31559471 = 31559514
47 + 31559467 = 31559514
67 + 31559447 = 31559514
71 + 31559443 = 31559514
97 + 31559417 = 31559514
101 + 31559413 = 31559514
113 + 31559401 = 31559514

Showing the first eight; more decompositions exist.
