Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577818, here are decompositions:

37 + 33577781 = 33577818
97 + 33577721 = 33577818
101 + 33577717 = 33577818
167 + 33577651 = 33577818
181 + 33577637 = 33577818
271 + 33577547 = 33577818
317 + 33577501 = 33577818
359 + 33577459 = 33577818

Showing the first eight; more decompositions exist.
