Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555578, here are decompositions:

61 + 33555517 = 33555578
79 + 33555499 = 33555578
97 + 33555481 = 33555578
109 + 33555469 = 33555578
139 + 33555439 = 33555578
157 + 33555421 = 33555578
181 + 33555397 = 33555578
307 + 33555271 = 33555578

Showing the first eight; more decompositions exist.
