Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738920, here are decompositions:

83 + 8738837 = 8738920
107 + 8738813 = 8738920
137 + 8738783 = 8738920
191 + 8738729 = 8738920
353 + 8738567 = 8738920
521 + 8738399 = 8738920
557 + 8738363 = 8738920
569 + 8738351 = 8738920

Showing the first eight; more decompositions exist.
