Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581040, here are decompositions:

13 + 33581027 = 33581040
19 + 33581021 = 33581040
29 + 33581011 = 33581040
47 + 33580993 = 33581040
83 + 33580957 = 33581040
109 + 33580931 = 33581040
131 + 33580909 = 33581040
137 + 33580903 = 33581040

Showing the first eight; more decompositions exist.
