Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521078, here are decompositions:

139 + 33520939 = 33521078
277 + 33520801 = 33521078
397 + 33520681 = 33521078
457 + 33520621 = 33521078
601 + 33520477 = 33521078
607 + 33520471 = 33521078
709 + 33520369 = 33521078
757 + 33520321 = 33521078

Showing the first eight; more decompositions exist.
