Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521138, here are decompositions:

151 + 33520987 = 33521138
199 + 33520939 = 33521138
337 + 33520801 = 33521138
379 + 33520759 = 33521138
457 + 33520681 = 33521138
577 + 33520561 = 33521138
661 + 33520477 = 33521138
709 + 33520429 = 33521138

Showing the first eight; more decompositions exist.
