Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691488, here are decompositions:

7 + 8691481 = 8691488
19 + 8691469 = 8691488
37 + 8691451 = 8691488
97 + 8691391 = 8691488
241 + 8691247 = 8691488
277 + 8691211 = 8691488
331 + 8691157 = 8691488
397 + 8691091 = 8691488

Showing the first eight; more decompositions exist.
