Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26100, here are decompositions:

17 + 26083 = 26100
47 + 26053 = 26100
59 + 26041 = 26100
71 + 26029 = 26100
79 + 26021 = 26100
83 + 26017 = 26100
97 + 26003 = 26100
101 + 25999 = 26100

Showing the first eight; more decompositions exist.
