Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023148, here are decompositions:

41 + 1023107 = 1023148
47 + 1023101 = 1023148
101 + 1023047 = 1023148
107 + 1023041 = 1023148
167 + 1022981 = 1023148
257 + 1022891 = 1023148
311 + 1022837 = 1023148
419 + 1022729 = 1023148

Showing the first eight; more decompositions exist.
