Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526010, here are decompositions:

29 + 31525981 = 31526010
53 + 31525957 = 31526010
59 + 31525951 = 31526010
83 + 31525927 = 31526010
97 + 31525913 = 31526010
101 + 31525909 = 31526010
107 + 31525903 = 31526010
193 + 31525817 = 31526010

Showing the first eight; more decompositions exist.
