Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559460, here are decompositions:

13 + 31559447 = 31559460
17 + 31559443 = 31559460
43 + 31559417 = 31559460
47 + 31559413 = 31559460
59 + 31559401 = 31559460
89 + 31559371 = 31559460
109 + 31559351 = 31559460
139 + 31559321 = 31559460

Showing the first eight; more decompositions exist.
