Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691632, here are decompositions:

43 + 8691589 = 8691632
151 + 8691481 = 8691632
163 + 8691469 = 8691632
181 + 8691451 = 8691632
199 + 8691433 = 8691632
241 + 8691391 = 8691632
409 + 8691223 = 8691632
421 + 8691211 = 8691632

Showing the first eight; more decompositions exist.
