Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558478, here are decompositions:

47 + 33558431 = 33558478
59 + 33558419 = 33558478
71 + 33558407 = 33558478
137 + 33558341 = 33558478
197 + 33558281 = 33558478
419 + 33558059 = 33558478
449 + 33558029 = 33558478
479 + 33557999 = 33558478

Showing the first eight; more decompositions exist.
