Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625890, here are decompositions:

41 + 33625849 = 33625890
47 + 33625843 = 33625890
59 + 33625831 = 33625890
73 + 33625817 = 33625890
139 + 33625751 = 33625890
167 + 33625723 = 33625890
211 + 33625679 = 33625890
223 + 33625667 = 33625890

Showing the first eight; more decompositions exist.
