Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023678, here are decompositions:

101 + 1023577 = 1023678
107 + 1023571 = 1023678
127 + 1023551 = 1023678
137 + 1023541 = 1023678
157 + 1023521 = 1023678
179 + 1023499 = 1023678
191 + 1023487 = 1023678
211 + 1023467 = 1023678

Showing the first eight; more decompositions exist.
