Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553664, here are decompositions:

3 + 33553661 = 33553664
7 + 33553657 = 33553664
13 + 33553651 = 33553664
31 + 33553633 = 33553664
127 + 33553537 = 33553664
307 + 33553357 = 33553664
337 + 33553327 = 33553664
523 + 33553141 = 33553664

Showing the first eight; more decompositions exist.
