Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513380, here are decompositions:

7 + 33513373 = 33513380
13 + 33513367 = 33513380
37 + 33513343 = 33513380
193 + 33513187 = 33513380
283 + 33513097 = 33513380
421 + 33512959 = 33513380
499 + 33512881 = 33513380
541 + 33512839 = 33513380

Showing the first eight; more decompositions exist.
