Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518380, here are decompositions:

29 + 33518351 = 33518380
47 + 33518333 = 33518380
53 + 33518327 = 33518380
83 + 33518297 = 33518380
107 + 33518273 = 33518380
113 + 33518267 = 33518380
167 + 33518213 = 33518380
239 + 33518141 = 33518380

Showing the first eight; more decompositions exist.
