Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554638, here are decompositions:

59 + 33554579 = 33554638
137 + 33554501 = 33554638
347 + 33554291 = 33554638
389 + 33554249 = 33554638
479 + 33554159 = 33554638
587 + 33554051 = 33554638
617 + 33554021 = 33554638
647 + 33553991 = 33554638

Showing the first eight; more decompositions exist.
