Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487078, here are decompositions:

17 + 33487061 = 33487078
29 + 33487049 = 33487078
47 + 33487031 = 33487078
137 + 33486941 = 33487078
311 + 33486767 = 33487078
347 + 33486731 = 33487078
467 + 33486611 = 33487078
491 + 33486587 = 33487078

Showing the first eight; more decompositions exist.
