Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620742, here are decompositions:

53 + 33620689 = 33620742
61 + 33620681 = 33620742
83 + 33620659 = 33620742
149 + 33620593 = 33620742
151 + 33620591 = 33620742
163 + 33620579 = 33620742
179 + 33620563 = 33620742
229 + 33620513 = 33620742

Showing the first eight; more decompositions exist.
