Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557278, here are decompositions:

191 + 33557087 = 33557278
269 + 33557009 = 33557278
317 + 33556961 = 33557278
389 + 33556889 = 33557278
401 + 33556877 = 33557278
431 + 33556847 = 33557278
467 + 33556811 = 33557278
509 + 33556769 = 33557278

Showing the first eight; more decompositions exist.
