Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654388, here are decompositions:

7 + 8654381 = 8654388
31 + 8654357 = 8654388
37 + 8654351 = 8654388
89 + 8654299 = 8654388
101 + 8654287 = 8654388
107 + 8654281 = 8654388
131 + 8654257 = 8654388
139 + 8654249 = 8654388

Showing the first eight; more decompositions exist.
