Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531618, here are decompositions:

5 + 33531613 = 33531618
7 + 33531611 = 33531618
31 + 33531587 = 33531618
41 + 33531577 = 33531618
59 + 33531559 = 33531618
139 + 33531479 = 33531618
149 + 33531469 = 33531618
151 + 33531467 = 33531618

Showing the first eight; more decompositions exist.
