Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517820, here are decompositions:

67 + 33517753 = 33517820
73 + 33517747 = 33517820
79 + 33517741 = 33517820
109 + 33517711 = 33517820
139 + 33517681 = 33517820
181 + 33517639 = 33517820
283 + 33517537 = 33517820
307 + 33517513 = 33517820

Showing the first eight; more decompositions exist.
