Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559466, here are decompositions:

19 + 31559447 = 31559466
23 + 31559443 = 31559466
53 + 31559413 = 31559466
83 + 31559383 = 31559466
149 + 31559317 = 31559466
227 + 31559239 = 31559466
277 + 31559189 = 31559466
317 + 31559149 = 31559466

Showing the first eight; more decompositions exist.
