Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697438, here are decompositions:

5 + 8697433 = 8697438
31 + 8697407 = 8697438
59 + 8697379 = 8697438
137 + 8697301 = 8697438
199 + 8697239 = 8697438
311 + 8697127 = 8697438
331 + 8697107 = 8697438
349 + 8697089 = 8697438

Showing the first eight; more decompositions exist.
