Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559454, here are decompositions:

7 + 31559447 = 31559454
11 + 31559443 = 31559454
37 + 31559417 = 31559454
41 + 31559413 = 31559454
53 + 31559401 = 31559454
71 + 31559383 = 31559454
83 + 31559371 = 31559454
103 + 31559351 = 31559454

Showing the first eight; more decompositions exist.
