Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517808, here are decompositions:

61 + 33517747 = 33517808
67 + 33517741 = 33517808
97 + 33517711 = 33517808
127 + 33517681 = 33517808
157 + 33517651 = 33517808
271 + 33517537 = 33517808
277 + 33517531 = 33517808
397 + 33517411 = 33517808

Showing the first eight; more decompositions exist.
