Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477980, here are decompositions:

97 + 33477883 = 33477980
163 + 33477817 = 33477980
331 + 33477649 = 33477980
337 + 33477643 = 33477980
421 + 33477559 = 33477980
457 + 33477523 = 33477980
463 + 33477517 = 33477980
499 + 33477481 = 33477980

Showing the first eight; more decompositions exist.
