Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485128, here are decompositions:

29 + 33485099 = 33485128
71 + 33485057 = 33485128
107 + 33485021 = 33485128
251 + 33484877 = 33485128
317 + 33484811 = 33485128
359 + 33484769 = 33485128
419 + 33484709 = 33485128
491 + 33484637 = 33485128

Showing the first eight; more decompositions exist.
