Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559484, here are decompositions:

13 + 31559471 = 31559484
17 + 31559467 = 31559484
37 + 31559447 = 31559484
41 + 31559443 = 31559484
67 + 31559417 = 31559484
71 + 31559413 = 31559484
83 + 31559401 = 31559484
101 + 31559383 = 31559484

Showing the first eight; more decompositions exist.
