Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515618, here are decompositions:

79 + 33515539 = 33515618
109 + 33515509 = 33515618
181 + 33515437 = 33515618
277 + 33515341 = 33515618
541 + 33515077 = 33515618
691 + 33514927 = 33515618
751 + 33514867 = 33515618
1009 + 33514609 = 33515618

Showing the first eight; more decompositions exist.
