Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489440, here are decompositions:

7 + 33489433 = 33489440
79 + 33489361 = 33489440
157 + 33489283 = 33489440
199 + 33489241 = 33489440
331 + 33489109 = 33489440
337 + 33489103 = 33489440
367 + 33489073 = 33489440
463 + 33488977 = 33489440

Showing the first eight; more decompositions exist.
