Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513890, here are decompositions:

13 + 33513877 = 33513890
31 + 33513859 = 33513890
79 + 33513811 = 33513890
229 + 33513661 = 33513890
331 + 33513559 = 33513890
349 + 33513541 = 33513890
433 + 33513457 = 33513890
523 + 33513367 = 33513890

Showing the first eight; more decompositions exist.
