Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555390, here are decompositions:

7 + 33555383 = 33555390
13 + 33555377 = 33555390
17 + 33555373 = 33555390
73 + 33555317 = 33555390
97 + 33555293 = 33555390
101 + 33555289 = 33555390
103 + 33555287 = 33555390
107 + 33555283 = 33555390

Showing the first eight; more decompositions exist.
