Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581658, here are decompositions:

37 + 33581621 = 33581658
41 + 33581617 = 33581658
59 + 33581599 = 33581658
137 + 33581521 = 33581658
167 + 33581491 = 33581658
277 + 33581381 = 33581658
307 + 33581351 = 33581658
337 + 33581321 = 33581658

Showing the first eight; more decompositions exist.
