Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620178, here are decompositions:

19 + 33620159 = 33620178
127 + 33620051 = 33620178
139 + 33620039 = 33620178
197 + 33619981 = 33620178
199 + 33619979 = 33620178
331 + 33619847 = 33620178
367 + 33619811 = 33620178
379 + 33619799 = 33620178

Showing the first eight; more decompositions exist.
