Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591820, here are decompositions:

83 + 33591737 = 33591820
137 + 33591683 = 33591820
167 + 33591653 = 33591820
173 + 33591647 = 33591820
179 + 33591641 = 33591820
191 + 33591629 = 33591820
293 + 33591527 = 33591820
419 + 33591401 = 33591820

Showing the first eight; more decompositions exist.
