Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496136, here are decompositions:

13 + 31496123 = 31496136
17 + 31496119 = 31496136
37 + 31496099 = 31496136
53 + 31496083 = 31496136
79 + 31496057 = 31496136
109 + 31496027 = 31496136
157 + 31495979 = 31496136
239 + 31495897 = 31496136

Showing the first eight; more decompositions exist.
