Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553820, here are decompositions:

61 + 33553759 = 33553820
73 + 33553747 = 33553820
127 + 33553693 = 33553820
163 + 33553657 = 33553820
271 + 33553549 = 33553820
283 + 33553537 = 33553820
331 + 33553489 = 33553820
457 + 33553363 = 33553820

Showing the first eight; more decompositions exist.
