Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747862, here are decompositions:

5 + 8747857 = 8747862
31 + 8747831 = 8747862
43 + 8747819 = 8747862
59 + 8747803 = 8747862
73 + 8747789 = 8747862
103 + 8747759 = 8747862
139 + 8747723 = 8747862
173 + 8747689 = 8747862

Showing the first eight; more decompositions exist.
