Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747494, here are decompositions:

5 + 8747489 = 8747494
11 + 8747483 = 8747494
23 + 8747471 = 8747494
53 + 8747441 = 8747494
71 + 8747423 = 8747494
113 + 8747381 = 8747494
167 + 8747327 = 8747494
233 + 8747261 = 8747494

Showing the first eight; more decompositions exist.
