Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581972, here are decompositions:

103 + 33581869 = 33581972
181 + 33581791 = 33581972
211 + 33581761 = 33581972
373 + 33581599 = 33581972
643 + 33581329 = 33581972
673 + 33581299 = 33581972
691 + 33581281 = 33581972
709 + 33581263 = 33581972

Showing the first eight; more decompositions exist.
