Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487558, here are decompositions:

47 + 33487511 = 33487558
107 + 33487451 = 33487558
239 + 33487319 = 33487558
257 + 33487301 = 33487558
281 + 33487277 = 33487558
311 + 33487247 = 33487558
509 + 33487049 = 33487558
617 + 33486941 = 33487558

Showing the first eight; more decompositions exist.
