Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487378, here are decompositions:

59 + 33487319 = 33487378
101 + 33487277 = 33487378
107 + 33487271 = 33487378
131 + 33487247 = 33487378
191 + 33487187 = 33487378
227 + 33487151 = 33487378
257 + 33487121 = 33487378
317 + 33487061 = 33487378

Showing the first eight; more decompositions exist.
