Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587790, here are decompositions:

29 + 33587761 = 33587790
53 + 33587737 = 33587790
59 + 33587731 = 33587790
83 + 33587707 = 33587790
107 + 33587683 = 33587790
113 + 33587677 = 33587790
157 + 33587633 = 33587790
233 + 33587557 = 33587790

Showing the first eight; more decompositions exist.
