Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488638, here are decompositions:

11 + 33488627 = 33488638
89 + 33488549 = 33488638
101 + 33488537 = 33488638
137 + 33488501 = 33488638
167 + 33488471 = 33488638
257 + 33488381 = 33488638
269 + 33488369 = 33488638
761 + 33487877 = 33488638

Showing the first eight; more decompositions exist.
