Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491240, here are decompositions:

7 + 33491233 = 33491240
19 + 33491221 = 33491240
37 + 33491203 = 33491240
199 + 33491041 = 33491240
241 + 33490999 = 33491240
313 + 33490927 = 33491240
397 + 33490843 = 33491240
439 + 33490801 = 33491240

Showing the first eight; more decompositions exist.
