Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023690, here are decompositions:

37 + 1023653 = 1023690
47 + 1023643 = 1023690
89 + 1023601 = 1023690
113 + 1023577 = 1023690
139 + 1023551 = 1023690
149 + 1023541 = 1023690
191 + 1023499 = 1023690
223 + 1023467 = 1023690

Showing the first eight; more decompositions exist.
