Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556802, here are decompositions:

23 + 31556779 = 31556802
31 + 31556771 = 31556802
61 + 31556741 = 31556802
149 + 31556653 = 31556802
163 + 31556639 = 31556802
313 + 31556489 = 31556802
379 + 31556423 = 31556802
421 + 31556381 = 31556802

Showing the first eight; more decompositions exist.
