Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489866, here are decompositions:

37 + 33489829 = 33489866
97 + 33489769 = 33489866
103 + 33489763 = 33489866
127 + 33489739 = 33489866
139 + 33489727 = 33489866
283 + 33489583 = 33489866
307 + 33489559 = 33489866
433 + 33489433 = 33489866

Showing the first eight; more decompositions exist.
