Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691798, here are decompositions:

47 + 8691751 = 8691798
67 + 8691731 = 8691798
109 + 8691689 = 8691798
131 + 8691667 = 8691798
211 + 8691587 = 8691798
257 + 8691541 = 8691798
317 + 8691481 = 8691798
347 + 8691451 = 8691798

Showing the first eight; more decompositions exist.
