Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26320, here are decompositions:

3 + 26317 = 26320
11 + 26309 = 26320
23 + 26297 = 26320
53 + 26267 = 26320
59 + 26261 = 26320
71 + 26249 = 26320
83 + 26237 = 26320
131 + 26189 = 26320

Showing the first eight; more decompositions exist.
