Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533926, here are decompositions:

3 + 31533923 = 31533926
7 + 31533919 = 31533926
79 + 31533847 = 31533926
97 + 31533829 = 31533926
103 + 31533823 = 31533926
157 + 31533769 = 31533926
163 + 31533763 = 31533926
313 + 31533613 = 31533926

Showing the first eight; more decompositions exist.
