Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587780, here are decompositions:

19 + 33587761 = 33587780
43 + 33587737 = 33587780
73 + 33587707 = 33587780
97 + 33587683 = 33587780
103 + 33587677 = 33587780
199 + 33587581 = 33587780
223 + 33587557 = 33587780
229 + 33587551 = 33587780

Showing the first eight; more decompositions exist.
