Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518042, here are decompositions:

13 + 33518029 = 33518042
31 + 33518011 = 33518042
139 + 33517903 = 33518042
163 + 33517879 = 33518042
193 + 33517849 = 33518042
331 + 33517711 = 33518042
409 + 33517633 = 33518042
631 + 33517411 = 33518042

Showing the first eight; more decompositions exist.
