Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531638, here are decompositions:

61 + 33531577 = 33531638
79 + 33531559 = 33531638
97 + 33531541 = 33531638
139 + 33531499 = 33531638
199 + 33531439 = 33531638
211 + 33531427 = 33531638
241 + 33531397 = 33531638
409 + 33531229 = 33531638

Showing the first eight; more decompositions exist.
