Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747838, here are decompositions:

7 + 8747831 = 8747838
19 + 8747819 = 8747838
31 + 8747807 = 8747838
61 + 8747777 = 8747838
79 + 8747759 = 8747838
101 + 8747737 = 8747838
137 + 8747701 = 8747838
149 + 8747689 = 8747838

Showing the first eight; more decompositions exist.
