Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554666, here are decompositions:

73 + 33554593 = 33554666
139 + 33554527 = 33554666
157 + 33554509 = 33554666
163 + 33554503 = 33554666
193 + 33554473 = 33554666
199 + 33554467 = 33554666
283 + 33554383 = 33554666
349 + 33554317 = 33554666

Showing the first eight; more decompositions exist.
