Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518580, here are decompositions:

41 + 33518539 = 33518580
83 + 33518497 = 33518580
89 + 33518491 = 33518580
127 + 33518453 = 33518580
131 + 33518449 = 33518580
163 + 33518417 = 33518580
191 + 33518389 = 33518580
229 + 33518351 = 33518580

Showing the first eight; more decompositions exist.
