Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489220, here are decompositions:

41 + 33489179 = 33489220
173 + 33489047 = 33489220
353 + 33488867 = 33489220
383 + 33488837 = 33489220
431 + 33488789 = 33489220
449 + 33488771 = 33489220
491 + 33488729 = 33489220
503 + 33488717 = 33489220

Showing the first eight; more decompositions exist.
