Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68100, here are decompositions:

13 + 68087 = 68100
29 + 68071 = 68100
41 + 68059 = 68100
47 + 68053 = 68100
59 + 68041 = 68100
107 + 67993 = 68100
113 + 67987 = 68100
139 + 67961 = 68100

Showing the first eight; more decompositions exist.
