Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491420, here are decompositions:

3 + 33491417 = 33491420
199 + 33491221 = 33491420
271 + 33491149 = 33491420
379 + 33491041 = 33491420
421 + 33490999 = 33491420
433 + 33490987 = 33491420
439 + 33490981 = 33491420
577 + 33490843 = 33491420

Showing the first eight; more decompositions exist.
