Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537894, here are decompositions:

31 + 33537863 = 33537894
37 + 33537857 = 33537894
97 + 33537797 = 33537894
127 + 33537767 = 33537894
193 + 33537701 = 33537894
211 + 33537683 = 33537894
281 + 33537613 = 33537894
337 + 33537557 = 33537894

Showing the first eight; more decompositions exist.
