Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743788, here are decompositions:

17 + 8743771 = 8743788
19 + 8743769 = 8743788
41 + 8743747 = 8743788
71 + 8743717 = 8743788
107 + 8743681 = 8743788
149 + 8743639 = 8743788
167 + 8743621 = 8743788
191 + 8743597 = 8743788

Showing the first eight; more decompositions exist.
