Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587742, here are decompositions:

5 + 33587737 = 33587742
11 + 33587731 = 33587742
59 + 33587683 = 33587742
73 + 33587669 = 33587742
109 + 33587633 = 33587742
191 + 33587551 = 33587742
193 + 33587549 = 33587742
229 + 33587513 = 33587742

Showing the first eight; more decompositions exist.
