Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747892, here are decompositions:

29 + 8747863 = 8747892
61 + 8747831 = 8747892
73 + 8747819 = 8747892
89 + 8747803 = 8747892
103 + 8747789 = 8747892
149 + 8747743 = 8747892
191 + 8747701 = 8747892
239 + 8747653 = 8747892

Showing the first eight; more decompositions exist.
