Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691274, here are decompositions:

5 + 8691269 = 8691274
23 + 8691251 = 8691274
107 + 8691167 = 8691274
173 + 8691101 = 8691274
311 + 8690963 = 8691274
353 + 8690921 = 8691274
461 + 8690813 = 8691274
491 + 8690783 = 8691274

Showing the first eight; more decompositions exist.
