Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491438, here are decompositions:

67 + 33491371 = 33491438
397 + 33491041 = 33491438
439 + 33490999 = 33491438
457 + 33490981 = 33491438
661 + 33490777 = 33491438
691 + 33490747 = 33491438
811 + 33490627 = 33491438
859 + 33490579 = 33491438

Showing the first eight; more decompositions exist.
