Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042342, here are decompositions:

11 + 1042331 = 1042342
71 + 1042271 = 1042342
83 + 1042259 = 1042342
101 + 1042241 = 1042342
131 + 1042211 = 1042342
149 + 1042193 = 1042342
233 + 1042109 = 1042342
239 + 1042103 = 1042342

Showing the first eight; more decompositions exist.
