Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042420, here are decompositions:

47 + 1042373 = 1042420
89 + 1042331 = 1042420
149 + 1042271 = 1042420
179 + 1042241 = 1042420
227 + 1042193 = 1042420
233 + 1042187 = 1042420
311 + 1042109 = 1042420
317 + 1042103 = 1042420

Showing the first eight; more decompositions exist.
