Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700100, here are decompositions:

29 + 8700071 = 8700100
41 + 8700059 = 8700100
53 + 8700047 = 8700100
89 + 8700011 = 8700100
107 + 8699993 = 8700100
131 + 8699969 = 8700100
293 + 8699807 = 8700100
347 + 8699753 = 8700100

Showing the first eight; more decompositions exist.
