Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565054, here are decompositions:

7 + 31565047 = 31565054
13 + 31565041 = 31565054
127 + 31564927 = 31565054
163 + 31564891 = 31565054
181 + 31564873 = 31565054
223 + 31564831 = 31565054
331 + 31564723 = 31565054
397 + 31564657 = 31565054

Showing the first eight; more decompositions exist.
