Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538440, here are decompositions:

37 + 33538403 = 33538440
53 + 33538387 = 33538440
73 + 33538367 = 33538440
97 + 33538343 = 33538440
101 + 33538339 = 33538440
113 + 33538327 = 33538440
127 + 33538313 = 33538440
137 + 33538303 = 33538440

Showing the first eight; more decompositions exist.
