Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578440, here are decompositions:

3 + 33578437 = 33578440
11 + 33578429 = 33578440
17 + 33578423 = 33578440
29 + 33578411 = 33578440
53 + 33578387 = 33578440
149 + 33578291 = 33578440
167 + 33578273 = 33578440
173 + 33578267 = 33578440

Showing the first eight; more decompositions exist.
