Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555642, here are decompositions:

13 + 33555629 = 33555642
31 + 33555611 = 33555642
59 + 33555583 = 33555642
79 + 33555563 = 33555642
89 + 33555553 = 33555642
149 + 33555493 = 33555642
173 + 33555469 = 33555642
181 + 33555461 = 33555642

Showing the first eight; more decompositions exist.
