Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564952, here are decompositions:

19 + 31564933 = 31564952
31 + 31564921 = 31564952
61 + 31564891 = 31564952
73 + 31564879 = 31564952
79 + 31564873 = 31564952
103 + 31564849 = 31564952
229 + 31564723 = 31564952
283 + 31564669 = 31564952

Showing the first eight; more decompositions exist.
