Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557126, here are decompositions:

67 + 557059 = 557126
109 + 557017 = 557126
127 + 556999 = 557126
139 + 556987 = 557126
277 + 556849 = 557126
307 + 556819 = 557126
337 + 556789 = 557126
373 + 556753 = 557126

Showing the first eight; more decompositions exist.
