Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515820, here are decompositions:

7 + 33515813 = 33515820
17 + 33515803 = 33515820
47 + 33515773 = 33515820
61 + 33515759 = 33515820
101 + 33515719 = 33515820
109 + 33515711 = 33515820
113 + 33515707 = 33515820
127 + 33515693 = 33515820

Showing the first eight; more decompositions exist.
