Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550778, here are decompositions:

61 + 550717 = 550778
127 + 550651 = 550778
157 + 550621 = 550778
307 + 550471 = 550778
331 + 550447 = 550778
337 + 550441 = 550778
409 + 550369 = 550778
499 + 550279 = 550778

Showing the first eight; more decompositions exist.
