Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556500, here are decompositions:

7 + 33556493 = 33556500
17 + 33556483 = 33556500
41 + 33556459 = 33556500
71 + 33556429 = 33556500
97 + 33556403 = 33556500
101 + 33556399 = 33556500
139 + 33556361 = 33556500
157 + 33556343 = 33556500

Showing the first eight; more decompositions exist.
