Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042340, here are decompositions:

7 + 1042333 = 1042340
31 + 1042309 = 1042340
67 + 1042273 = 1042340
73 + 1042267 = 1042340
97 + 1042243 = 1042340
157 + 1042183 = 1042340
199 + 1042141 = 1042340
241 + 1042099 = 1042340

Showing the first eight; more decompositions exist.
