Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538380, here are decompositions:

13 + 33538367 = 33538380
37 + 33538343 = 33538380
41 + 33538339 = 33538380
53 + 33538327 = 33538380
59 + 33538321 = 33538380
67 + 33538313 = 33538380
107 + 33538273 = 33538380
149 + 33538231 = 33538380

Showing the first eight; more decompositions exist.
