Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617878, here are decompositions:

59 + 33617819 = 33617878
71 + 33617807 = 33617878
101 + 33617777 = 33617878
131 + 33617747 = 33617878
149 + 33617729 = 33617878
167 + 33617711 = 33617878
257 + 33617621 = 33617878
317 + 33617561 = 33617878

Showing the first eight; more decompositions exist.
