Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511578, here are decompositions:

7 + 33511571 = 33511578
17 + 33511561 = 33511578
29 + 33511549 = 33511578
31 + 33511547 = 33511578
47 + 33511531 = 33511578
59 + 33511519 = 33511578
71 + 33511507 = 33511578
131 + 33511447 = 33511578

Showing the first eight; more decompositions exist.
