Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556818, here are decompositions:

7 + 33556811 = 33556818
107 + 33556711 = 33556818
137 + 33556681 = 33556818
271 + 33556547 = 33556818
311 + 33556507 = 33556818
359 + 33556459 = 33556818
389 + 33556429 = 33556818
419 + 33556399 = 33556818

Showing the first eight; more decompositions exist.
