Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559826, here are decompositions:

5 + 31559821 = 31559826
13 + 31559813 = 31559826
17 + 31559809 = 31559826
43 + 31559783 = 31559826
107 + 31559719 = 31559826
127 + 31559699 = 31559826
139 + 31559687 = 31559826
149 + 31559677 = 31559826

Showing the first eight; more decompositions exist.
