Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488658, here are decompositions:

11 + 33488647 = 33488658
19 + 33488639 = 33488658
31 + 33488627 = 33488658
59 + 33488599 = 33488658
89 + 33488569 = 33488658
101 + 33488557 = 33488658
109 + 33488549 = 33488658
149 + 33488509 = 33488658

Showing the first eight; more decompositions exist.
