Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33510880, here are decompositions:

3 + 33510877 = 33510880
47 + 33510833 = 33510880
59 + 33510821 = 33510880
83 + 33510797 = 33510880
101 + 33510779 = 33510880
113 + 33510767 = 33510880
131 + 33510749 = 33510880
173 + 33510707 = 33510880

Showing the first eight; more decompositions exist.
