Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042126, here are decompositions:

3 + 1042123 = 1042126
5 + 1042121 = 1042126
17 + 1042109 = 1042126
23 + 1042103 = 1042126
83 + 1042043 = 1042126
233 + 1041893 = 1042126
257 + 1041869 = 1042126
263 + 1041863 = 1042126

Showing the first eight; more decompositions exist.
