Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538618, here are decompositions:

17 + 33538601 = 33538618
101 + 33538517 = 33538618
107 + 33538511 = 33538618
137 + 33538481 = 33538618
149 + 33538469 = 33538618
251 + 33538367 = 33538618
359 + 33538259 = 33538618
401 + 33538217 = 33538618

Showing the first eight; more decompositions exist.
