Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500780, here are decompositions:

13 + 33500767 = 33500780
97 + 33500683 = 33500780
109 + 33500671 = 33500780
127 + 33500653 = 33500780
139 + 33500641 = 33500780
163 + 33500617 = 33500780
193 + 33500587 = 33500780
283 + 33500497 = 33500780

Showing the first eight; more decompositions exist.
