Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553826, here are decompositions:

19 + 31553807 = 31553826
23 + 31553803 = 31553826
43 + 31553783 = 31553826
67 + 31553759 = 31553826
97 + 31553729 = 31553826
107 + 31553719 = 31553826
163 + 31553663 = 31553826
167 + 31553659 = 31553826

Showing the first eight; more decompositions exist.
