Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509380, here are decompositions:

53 + 33509327 = 33509380
89 + 33509291 = 33509380
101 + 33509279 = 33509380
137 + 33509243 = 33509380
251 + 33509129 = 33509380
461 + 33508919 = 33509380
479 + 33508901 = 33509380
521 + 33508859 = 33509380

Showing the first eight; more decompositions exist.
