Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559914, here are decompositions:

3 + 31559911 = 31559914
53 + 31559861 = 31559914
83 + 31559831 = 31559914
101 + 31559813 = 31559914
131 + 31559783 = 31559914
137 + 31559777 = 31559914
227 + 31559687 = 31559914
233 + 31559681 = 31559914

Showing the first eight; more decompositions exist.
