Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747944, here are decompositions:

3 + 8747941 = 8747944
11 + 8747933 = 8747944
17 + 8747927 = 8747944
41 + 8747903 = 8747944
53 + 8747891 = 8747944
113 + 8747831 = 8747944
137 + 8747807 = 8747944
167 + 8747777 = 8747944

Showing the first eight; more decompositions exist.
