Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557140, here are decompositions:

53 + 33557087 = 33557140
83 + 33557057 = 33557140
131 + 33557009 = 33557140
179 + 33556961 = 33557140
251 + 33556889 = 33557140
263 + 33556877 = 33557140
293 + 33556847 = 33557140
317 + 33556823 = 33557140

Showing the first eight; more decompositions exist.
