Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621104, here are decompositions:

3 + 8621101 = 8621104
17 + 8621087 = 8621104
53 + 8621051 = 8621104
131 + 8620973 = 8621104
257 + 8620847 = 8621104
263 + 8620841 = 8621104
347 + 8620757 = 8621104
383 + 8620721 = 8621104

Showing the first eight; more decompositions exist.
