Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581906, here are decompositions:

37 + 33581869 = 33581906
139 + 33581767 = 33581906
199 + 33581707 = 33581906
229 + 33581677 = 33581906
307 + 33581599 = 33581906
577 + 33581329 = 33581906
607 + 33581299 = 33581906
619 + 33581287 = 33581906

Showing the first eight; more decompositions exist.
