Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043240, here are decompositions:

19 + 1043221 = 1043240
31 + 1043209 = 1043240
67 + 1043173 = 1043240
73 + 1043167 = 1043240
109 + 1043131 = 1043240
127 + 1043113 = 1043240
151 + 1043089 = 1043240
157 + 1043083 = 1043240

Showing the first eight; more decompositions exist.
