Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488538, here are decompositions:

29 + 33488509 = 33488538
37 + 33488501 = 33488538
47 + 33488491 = 33488538
59 + 33488479 = 33488538
67 + 33488471 = 33488538
71 + 33488467 = 33488538
89 + 33488449 = 33488538
131 + 33488407 = 33488538

Showing the first eight; more decompositions exist.
