Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638946, here are decompositions:

13 + 8638933 = 8638946
37 + 8638909 = 8638946
79 + 8638867 = 8638946
97 + 8638849 = 8638946
103 + 8638843 = 8638946
139 + 8638807 = 8638946
313 + 8638633 = 8638946
499 + 8638447 = 8638946

Showing the first eight; more decompositions exist.
