Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554640, here are decompositions:

47 + 33554593 = 33554640
59 + 33554581 = 33554640
61 + 33554579 = 33554640
113 + 33554527 = 33554640
131 + 33554509 = 33554640
137 + 33554503 = 33554640
139 + 33554501 = 33554640
167 + 33554473 = 33554640

Showing the first eight; more decompositions exist.
