Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638174, here are decompositions:

23 + 8638151 = 8638174
53 + 8638121 = 8638174
107 + 8638067 = 8638174
113 + 8638061 = 8638174
131 + 8638043 = 8638174
353 + 8637821 = 8638174
383 + 8637791 = 8638174
557 + 8637617 = 8638174

Showing the first eight; more decompositions exist.
