Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493780, here are decompositions:

3 + 33493777 = 33493780
107 + 33493673 = 33493780
167 + 33493613 = 33493780
179 + 33493601 = 33493780
239 + 33493541 = 33493780
251 + 33493529 = 33493780
389 + 33493391 = 33493780
557 + 33493223 = 33493780

Showing the first eight; more decompositions exist.
