Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555556, here are decompositions:

3 + 33555553 = 33555556
29 + 33555527 = 33555556
59 + 33555497 = 33555556
107 + 33555449 = 33555556
137 + 33555419 = 33555556
173 + 33555383 = 33555556
179 + 33555377 = 33555556
239 + 33555317 = 33555556

Showing the first eight; more decompositions exist.
