Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533806, here are decompositions:

37 + 31533769 = 31533806
43 + 31533763 = 31533806
193 + 31533613 = 31533806
307 + 31533499 = 31533806
397 + 31533409 = 31533806
463 + 31533343 = 31533806
547 + 31533259 = 31533806
673 + 31533133 = 31533806

Showing the first eight; more decompositions exist.
