Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581080, here are decompositions:

53 + 33581027 = 33581080
59 + 33581021 = 33581080
89 + 33580991 = 33581080
149 + 33580931 = 33581080
173 + 33580907 = 33581080
293 + 33580787 = 33581080
311 + 33580769 = 33581080
353 + 33580727 = 33581080

Showing the first eight; more decompositions exist.
