Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748100, here are decompositions:

3 + 8748097 = 8748100
83 + 8748017 = 8748100
89 + 8748011 = 8748100
113 + 8747987 = 8748100
167 + 8747933 = 8748100
173 + 8747927 = 8748100
197 + 8747903 = 8748100
269 + 8747831 = 8748100

Showing the first eight; more decompositions exist.
