Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747850, here are decompositions:

19 + 8747831 = 8747850
31 + 8747819 = 8747850
43 + 8747807 = 8747850
47 + 8747803 = 8747850
61 + 8747789 = 8747850
73 + 8747777 = 8747850
103 + 8747747 = 8747850
107 + 8747743 = 8747850

Showing the first eight; more decompositions exist.
