Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581042, here are decompositions:

31 + 33581011 = 33581042
139 + 33580903 = 33581042
151 + 33580891 = 33581042
163 + 33580879 = 33581042
193 + 33580849 = 33581042
223 + 33580819 = 33581042
241 + 33580801 = 33581042
349 + 33580693 = 33581042

Showing the first eight; more decompositions exist.
