Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600062, here are decompositions:

5 + 31600057 = 31600062
19 + 31600043 = 31600062
23 + 31600039 = 31600062
61 + 31600001 = 31600062
103 + 31599959 = 31600062
149 + 31599913 = 31600062
191 + 31599871 = 31600062
239 + 31599823 = 31600062

Showing the first eight; more decompositions exist.
