Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499780, here are decompositions:

3 + 33499777 = 33499780
11 + 33499769 = 33499780
23 + 33499757 = 33499780
29 + 33499751 = 33499780
59 + 33499721 = 33499780
89 + 33499691 = 33499780
131 + 33499649 = 33499780
137 + 33499643 = 33499780

Showing the first eight; more decompositions exist.
