Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26578, here are decompositions:

5 + 26573 = 26578
17 + 26561 = 26578
89 + 26489 = 26578
179 + 26399 = 26578
191 + 26387 = 26578
239 + 26339 = 26578
257 + 26321 = 26578
269 + 26309 = 26578

Showing the first eight; more decompositions exist.
