Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591812, here are decompositions:

43 + 33591769 = 33591812
73 + 33591739 = 33591812
109 + 33591703 = 33591812
193 + 33591619 = 33591812
313 + 33591499 = 33591812
349 + 33591463 = 33591812
409 + 33591403 = 33591812
523 + 33591289 = 33591812

Showing the first eight; more decompositions exist.
