Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517988, here are decompositions:

67 + 33517921 = 33517988
109 + 33517879 = 33517988
139 + 33517849 = 33517988
241 + 33517747 = 33517988
277 + 33517711 = 33517988
307 + 33517681 = 33517988
337 + 33517651 = 33517988
349 + 33517639 = 33517988

Showing the first eight; more decompositions exist.
