Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620878, here are decompositions:

59 + 33620819 = 33620878
89 + 33620789 = 33620878
197 + 33620681 = 33620878
251 + 33620627 = 33620878
257 + 33620621 = 33620878
281 + 33620597 = 33620878
419 + 33620459 = 33620878
449 + 33620429 = 33620878

Showing the first eight; more decompositions exist.
