Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042306, here are decompositions:

47 + 1042259 = 1042306
113 + 1042193 = 1042306
173 + 1042133 = 1042306
197 + 1042109 = 1042306
263 + 1042043 = 1042306
443 + 1041863 = 1042306
449 + 1041857 = 1042306
569 + 1041737 = 1042306

Showing the first eight; more decompositions exist.
