Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550784, here are decompositions:

67 + 550717 = 550784
127 + 550657 = 550784
163 + 550621 = 550784
271 + 550513 = 550784
313 + 550471 = 550784
337 + 550447 = 550784
433 + 550351 = 550784
571 + 550213 = 550784

Showing the first eight; more decompositions exist.
