Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521380, here are decompositions:

59 + 33521321 = 33521380
239 + 33521141 = 33521380
281 + 33521099 = 33521380
293 + 33521087 = 33521380
359 + 33521021 = 33521380
401 + 33520979 = 33521380
461 + 33520919 = 33521380
521 + 33520859 = 33521380

Showing the first eight; more decompositions exist.
