Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591786, here are decompositions:

17 + 33591769 = 33591786
29 + 33591757 = 33591786
47 + 33591739 = 33591786
83 + 33591703 = 33591786
103 + 33591683 = 33591786
127 + 33591659 = 33591786
139 + 33591647 = 33591786
149 + 33591637 = 33591786

Showing the first eight; more decompositions exist.
