Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488158, here are decompositions:

71 + 33488087 = 33488158
251 + 33487907 = 33488158
257 + 33487901 = 33488158
281 + 33487877 = 33488158
311 + 33487847 = 33488158
401 + 33487757 = 33488158
647 + 33487511 = 33488158
839 + 33487319 = 33488158

Showing the first eight; more decompositions exist.
