Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658100, here are decompositions:

41 + 8658059 = 8658100
83 + 8658017 = 8658100
131 + 8657969 = 8658100
167 + 8657933 = 8658100
173 + 8657927 = 8658100
197 + 8657903 = 8658100
251 + 8657849 = 8658100
317 + 8657783 = 8658100

Showing the first eight; more decompositions exist.
