Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490942, here are decompositions:

53 + 33490889 = 33490942
101 + 33490841 = 33490942
179 + 33490763 = 33490942
479 + 33490463 = 33490942
599 + 33490343 = 33490942
701 + 33490241 = 33490942
761 + 33490181 = 33490942
911 + 33490031 = 33490942

Showing the first eight; more decompositions exist.
