Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520786, here are decompositions:

3 + 33520783 = 33520786
23 + 33520763 = 33520786
137 + 33520649 = 33520786
317 + 33520469 = 33520786
347 + 33520439 = 33520786
389 + 33520397 = 33520786
419 + 33520367 = 33520786
503 + 33520283 = 33520786

Showing the first eight; more decompositions exist.
