Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654440, here are decompositions:

59 + 8654381 = 8654440
83 + 8654357 = 8654440
89 + 8654351 = 8654440
101 + 8654339 = 8654440
107 + 8654333 = 8654440
191 + 8654249 = 8654440
239 + 8654201 = 8654440
257 + 8654183 = 8654440

Showing the first eight; more decompositions exist.
