Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545288, here are decompositions:

37 + 33545251 = 33545288
61 + 33545227 = 33545288
97 + 33545191 = 33545288
349 + 33544939 = 33545288
367 + 33544921 = 33545288
421 + 33544867 = 33545288
571 + 33544717 = 33545288
577 + 33544711 = 33545288

Showing the first eight; more decompositions exist.
