Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487100, here are decompositions:

19 + 33487081 = 33487100
67 + 33487033 = 33487100
79 + 33487021 = 33487100
103 + 33486997 = 33487100
271 + 33486829 = 33487100
331 + 33486769 = 33487100
337 + 33486763 = 33487100
349 + 33486751 = 33487100

Showing the first eight; more decompositions exist.
