Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607820, here are decompositions:

3 + 33607817 = 33607820
19 + 33607801 = 33607820
67 + 33607753 = 33607820
73 + 33607747 = 33607820
109 + 33607711 = 33607820
157 + 33607663 = 33607820
331 + 33607489 = 33607820
349 + 33607471 = 33607820

Showing the first eight; more decompositions exist.
