Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489830, here are decompositions:

61 + 33489769 = 33489830
67 + 33489763 = 33489830
103 + 33489727 = 33489830
181 + 33489649 = 33489830
211 + 33489619 = 33489830
271 + 33489559 = 33489830
397 + 33489433 = 33489830
547 + 33489283 = 33489830

Showing the first eight; more decompositions exist.
