Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565084, here are decompositions:

7 + 31565077 = 31565084
37 + 31565047 = 31565084
43 + 31565041 = 31565084
151 + 31564933 = 31565084
157 + 31564927 = 31565084
163 + 31564921 = 31565084
193 + 31564891 = 31565084
211 + 31564873 = 31565084

Showing the first eight; more decompositions exist.
