Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564002, here are decompositions:

13 + 31563989 = 31564002
23 + 31563979 = 31564002
53 + 31563949 = 31564002
59 + 31563943 = 31564002
61 + 31563941 = 31564002
73 + 31563929 = 31564002
103 + 31563899 = 31564002
131 + 31563871 = 31564002

Showing the first eight; more decompositions exist.
