Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548826, here are decompositions:

3 + 31548823 = 31548826
59 + 31548767 = 31548826
83 + 31548743 = 31548826
149 + 31548677 = 31548826
167 + 31548659 = 31548826
173 + 31548653 = 31548826
233 + 31548593 = 31548826
263 + 31548563 = 31548826

Showing the first eight; more decompositions exist.
