Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478840, here are decompositions:

89 + 33478751 = 33478840
113 + 33478727 = 33478840
191 + 33478649 = 33478840
233 + 33478607 = 33478840
257 + 33478583 = 33478840
401 + 33478439 = 33478840
419 + 33478421 = 33478840
449 + 33478391 = 33478840

Showing the first eight; more decompositions exist.
