Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562064, here are decompositions:

7 + 31562057 = 31562064
11 + 31562053 = 31562064
31 + 31562033 = 31562064
41 + 31562023 = 31562064
47 + 31562017 = 31562064
71 + 31561993 = 31562064
97 + 31561967 = 31562064
137 + 31561927 = 31562064

Showing the first eight; more decompositions exist.
