Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556378, here are decompositions:

17 + 33556361 = 33556378
389 + 33555989 = 33556378
419 + 33555959 = 33556378
431 + 33555947 = 33556378
641 + 33555737 = 33556378
677 + 33555701 = 33556378
719 + 33555659 = 33556378
761 + 33555617 = 33556378

Showing the first eight; more decompositions exist.
