Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023658, here are decompositions:

5 + 1023653 = 1023658
101 + 1023557 = 1023658
107 + 1023551 = 1023658
137 + 1023521 = 1023658
191 + 1023467 = 1023658
197 + 1023461 = 1023658
239 + 1023419 = 1023658
269 + 1023389 = 1023658

Showing the first eight; more decompositions exist.
