Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743778, here are decompositions:

7 + 8743771 = 8743778
31 + 8743747 = 8743778
61 + 8743717 = 8743778
67 + 8743711 = 8743778
97 + 8743681 = 8743778
139 + 8743639 = 8743778
157 + 8743621 = 8743778
181 + 8743597 = 8743778

Showing the first eight; more decompositions exist.
