Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487738, here are decompositions:

5 + 33487733 = 33487738
107 + 33487631 = 33487738
131 + 33487607 = 33487738
227 + 33487511 = 33487738
419 + 33487319 = 33487738
461 + 33487277 = 33487738
467 + 33487271 = 33487738
491 + 33487247 = 33487738

Showing the first eight; more decompositions exist.
