Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491186, here are decompositions:

37 + 33491149 = 33491186
199 + 33490987 = 33491186
373 + 33490813 = 33491186
409 + 33490777 = 33491186
439 + 33490747 = 33491186
607 + 33490579 = 33491186
613 + 33490573 = 33491186
709 + 33490477 = 33491186

Showing the first eight; more decompositions exist.
