Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023166, here are decompositions:

3 + 1023163 = 1023166
59 + 1023107 = 1023166
83 + 1023083 = 1023166
233 + 1022933 = 1023166
317 + 1022849 = 1023166
593 + 1022573 = 1023166
647 + 1022519 = 1023166
653 + 1022513 = 1023166

Showing the first eight; more decompositions exist.
