Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747810, here are decompositions:

3 + 8747807 = 8747810
7 + 8747803 = 8747810
67 + 8747743 = 8747810
73 + 8747737 = 8747810
109 + 8747701 = 8747810
157 + 8747653 = 8747810
193 + 8747617 = 8747810
271 + 8747539 = 8747810

Showing the first eight; more decompositions exist.
