Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100268, here are decompositions:

31 + 100237 = 100268
61 + 100207 = 100268
79 + 100189 = 100268
139 + 100129 = 100268
199 + 100069 = 100268
211 + 100057 = 100268
277 + 99991 = 100268
307 + 99961 = 100268

Showing the first eight; more decompositions exist.
