Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8695778, here are decompositions:

31 + 8695747 = 8695778
97 + 8695681 = 8695778
127 + 8695651 = 8695778
139 + 8695639 = 8695778
229 + 8695549 = 8695778
277 + 8695501 = 8695778
367 + 8695411 = 8695778
379 + 8695399 = 8695778

Showing the first eight; more decompositions exist.
