Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564962, here are decompositions:

19 + 31564943 = 31564962
29 + 31564933 = 31564962
41 + 31564921 = 31564962
43 + 31564919 = 31564962
71 + 31564891 = 31564962
83 + 31564879 = 31564962
89 + 31564873 = 31564962
109 + 31564853 = 31564962

Showing the first eight; more decompositions exist.
