Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490840, here are decompositions:

23 + 33490817 = 33490840
59 + 33490781 = 33490840
233 + 33490607 = 33490840
293 + 33490547 = 33490840
311 + 33490529 = 33490840
431 + 33490409 = 33490840
443 + 33490397 = 33490840
479 + 33490361 = 33490840

Showing the first eight; more decompositions exist.
