Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023806, here are decompositions:

37 + 1023769 = 1023806
73 + 1023733 = 1023806
109 + 1023697 = 1023806
163 + 1023643 = 1023806
229 + 1023577 = 1023806
307 + 1023499 = 1023806
397 + 1023409 = 1023806
439 + 1023367 = 1023806

Showing the first eight; more decompositions exist.
