Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487380, here are decompositions:

37 + 33487343 = 33487380
61 + 33487319 = 33487380
67 + 33487313 = 33487380
71 + 33487309 = 33487380
79 + 33487301 = 33487380
103 + 33487277 = 33487380
107 + 33487273 = 33487380
109 + 33487271 = 33487380

Showing the first eight; more decompositions exist.
