Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023638, here are decompositions:

37 + 1023601 = 1023638
61 + 1023577 = 1023638
67 + 1023571 = 1023638
97 + 1023541 = 1023638
139 + 1023499 = 1023638
151 + 1023487 = 1023638
229 + 1023409 = 1023638
271 + 1023367 = 1023638

Showing the first eight; more decompositions exist.
