Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598826, here are decompositions:

37 + 31598789 = 31598826
43 + 31598783 = 31598826
47 + 31598779 = 31598826
73 + 31598753 = 31598826
109 + 31598717 = 31598826
139 + 31598687 = 31598826
157 + 31598669 = 31598826
179 + 31598647 = 31598826

Showing the first eight; more decompositions exist.
