Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528826, here are decompositions:

3 + 31528823 = 31528826
13 + 31528813 = 31528826
19 + 31528807 = 31528826
97 + 31528729 = 31528826
103 + 31528723 = 31528826
157 + 31528669 = 31528826
193 + 31528633 = 31528826
367 + 31528459 = 31528826

Showing the first eight; more decompositions exist.
