Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33603640, here are decompositions:

23 + 33603617 = 33603640
41 + 33603599 = 33603640
47 + 33603593 = 33603640
53 + 33603587 = 33603640
71 + 33603569 = 33603640
101 + 33603539 = 33603640
113 + 33603527 = 33603640
179 + 33603461 = 33603640

Showing the first eight; more decompositions exist.
