Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517978, here are decompositions:

71 + 33517907 = 33517978
107 + 33517871 = 33517978
167 + 33517811 = 33517978
281 + 33517697 = 33517978
359 + 33517619 = 33517978
419 + 33517559 = 33517978
479 + 33517499 = 33517978
509 + 33517469 = 33517978

Showing the first eight; more decompositions exist.
