Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523826, here are decompositions:

23 + 31523803 = 31523826
73 + 31523753 = 31523826
157 + 31523669 = 31523826
167 + 31523659 = 31523826
179 + 31523647 = 31523826
193 + 31523633 = 31523826
227 + 31523599 = 31523826
349 + 31523477 = 31523826

Showing the first eight; more decompositions exist.
