Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738020, here are decompositions:

41 + 8737979 = 8738020
149 + 8737871 = 8738020
191 + 8737829 = 8738020
257 + 8737763 = 8738020
311 + 8737709 = 8738020
353 + 8737667 = 8738020
443 + 8737577 = 8738020
449 + 8737571 = 8738020

Showing the first eight; more decompositions exist.
