Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530826, here are decompositions:

29 + 31530797 = 31530826
53 + 31530773 = 31530826
113 + 31530713 = 31530826
167 + 31530659 = 31530826
233 + 31530593 = 31530826
347 + 31530479 = 31530826
389 + 31530437 = 31530826
443 + 31530383 = 31530826

Showing the first eight; more decompositions exist.
