Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521480, here are decompositions:

19 + 33521461 = 33521480
43 + 33521437 = 33521480
79 + 33521401 = 33521480
397 + 33521083 = 33521480
541 + 33520939 = 33521480
859 + 33520621 = 33521480
877 + 33520603 = 33521480
919 + 33520561 = 33521480

Showing the first eight; more decompositions exist.
