Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023140, here are decompositions:

7 + 1023133 = 1023140
61 + 1023079 = 1023140
73 + 1023067 = 1023140
103 + 1023037 = 1023140
163 + 1022977 = 1023140
211 + 1022929 = 1023140
229 + 1022911 = 1023140
241 + 1022899 = 1023140

Showing the first eight; more decompositions exist.
