Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564914, here are decompositions:

23 + 31564891 = 31564914
41 + 31564873 = 31564914
61 + 31564853 = 31564914
83 + 31564831 = 31564914
107 + 31564807 = 31564914
191 + 31564723 = 31564914
193 + 31564721 = 31564914
257 + 31564657 = 31564914

Showing the first eight; more decompositions exist.
