Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747802, here are decompositions:

13 + 8747789 = 8747802
43 + 8747759 = 8747802
59 + 8747743 = 8747802
79 + 8747723 = 8747802
101 + 8747701 = 8747802
113 + 8747689 = 8747802
149 + 8747653 = 8747802
179 + 8747623 = 8747802

Showing the first eight; more decompositions exist.
