Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581900, here are decompositions:

31 + 33581869 = 33581900
43 + 33581857 = 33581900
109 + 33581791 = 33581900
139 + 33581761 = 33581900
193 + 33581707 = 33581900
223 + 33581677 = 33581900
229 + 33581671 = 33581900
283 + 33581617 = 33581900

Showing the first eight; more decompositions exist.
