Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620142, here are decompositions:

13 + 33620129 = 33620142
29 + 33620113 = 33620142
103 + 33620039 = 33620142
139 + 33620003 = 33620142
163 + 33619979 = 33620142
223 + 33619919 = 33620142
331 + 33619811 = 33620142
379 + 33619763 = 33620142

Showing the first eight; more decompositions exist.
