Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526136, here are decompositions:

53 + 31526083 = 31526136
67 + 31526069 = 31526136
73 + 31526063 = 31526136
79 + 31526057 = 31526136
179 + 31525957 = 31526136
223 + 31525913 = 31526136
227 + 31525909 = 31526136
233 + 31525903 = 31526136

Showing the first eight; more decompositions exist.
