Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019558, here are decompositions:

79 + 1019479 = 1019558
109 + 1019449 = 1019558
181 + 1019377 = 1019558
229 + 1019329 = 1019558
277 + 1019281 = 1019558
307 + 1019251 = 1019558
349 + 1019209 = 1019558
439 + 1019119 = 1019558

Showing the first eight; more decompositions exist.
