Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491528, here are decompositions:

61 + 33491467 = 33491528
67 + 33491461 = 33491528
157 + 33491371 = 33491528
307 + 33491221 = 33491528
379 + 33491149 = 33491528
487 + 33491041 = 33491528
541 + 33490987 = 33491528
547 + 33490981 = 33491528

Showing the first eight; more decompositions exist.
