Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555618, here are decompositions:

7 + 33555611 = 33555618
101 + 33555517 = 33555618
137 + 33555481 = 33555618
149 + 33555469 = 33555618
157 + 33555461 = 33555618
179 + 33555439 = 33555618
197 + 33555421 = 33555618
199 + 33555419 = 33555618

Showing the first eight; more decompositions exist.
