Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478642, here are decompositions:

59 + 33478583 = 33478642
173 + 33478469 = 33478642
251 + 33478391 = 33478642
311 + 33478331 = 33478642
359 + 33478283 = 33478642
443 + 33478199 = 33478642
479 + 33478163 = 33478642
521 + 33478121 = 33478642

Showing the first eight; more decompositions exist.
