Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559112, here are decompositions:

19 + 31559093 = 31559112
31 + 31559081 = 31559112
41 + 31559071 = 31559112
43 + 31559069 = 31559112
61 + 31559051 = 31559112
139 + 31558973 = 31559112
149 + 31558963 = 31559112
173 + 31558939 = 31559112

Showing the first eight; more decompositions exist.
