Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691554, here are decompositions:

13 + 8691541 = 8691554
73 + 8691481 = 8691554
103 + 8691451 = 8691554
163 + 8691391 = 8691554
181 + 8691373 = 8691554
241 + 8691313 = 8691554
307 + 8691247 = 8691554
331 + 8691223 = 8691554

Showing the first eight; more decompositions exist.
