Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491198, here are decompositions:

157 + 33491041 = 33491198
199 + 33490999 = 33491198
211 + 33490987 = 33491198
271 + 33490927 = 33491198
397 + 33490801 = 33491198
421 + 33490777 = 33491198
571 + 33490627 = 33491198
619 + 33490579 = 33491198

Showing the first eight; more decompositions exist.
