Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735778, here are decompositions:

17 + 8735761 = 8735778
67 + 8735711 = 8735778
97 + 8735681 = 8735778
101 + 8735677 = 8735778
157 + 8735621 = 8735778
197 + 8735581 = 8735778
229 + 8735549 = 8735778
241 + 8735537 = 8735778

Showing the first eight; more decompositions exist.
