Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33580640, here are decompositions:

7 + 33580633 = 33580640
43 + 33580597 = 33580640
109 + 33580531 = 33580640
151 + 33580489 = 33580640
193 + 33580447 = 33580640
241 + 33580399 = 33580640
367 + 33580273 = 33580640
397 + 33580243 = 33580640

Showing the first eight; more decompositions exist.
