Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505890, here are decompositions:

7 + 33505883 = 33505890
23 + 33505867 = 33505890
31 + 33505859 = 33505890
37 + 33505853 = 33505890
43 + 33505847 = 33505890
101 + 33505789 = 33505890
109 + 33505781 = 33505890
113 + 33505777 = 33505890

Showing the first eight; more decompositions exist.
