Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009640, here are decompositions:

3 + 1009637 = 1009640
13 + 1009627 = 1009640
19 + 1009621 = 1009640
31 + 1009609 = 1009640
67 + 1009573 = 1009640
103 + 1009537 = 1009640
109 + 1009531 = 1009640
139 + 1009501 = 1009640

Showing the first eight; more decompositions exist.
