Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487148, here are decompositions:

31 + 33487117 = 33487148
67 + 33487081 = 33487148
127 + 33487021 = 33487148
151 + 33486997 = 33487148
307 + 33486841 = 33487148
349 + 33486799 = 33487148
379 + 33486769 = 33487148
397 + 33486751 = 33487148

Showing the first eight; more decompositions exist.
