Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26590, here are decompositions:

17 + 26573 = 26590
29 + 26561 = 26590
89 + 26501 = 26590
101 + 26489 = 26590
131 + 26459 = 26590
167 + 26423 = 26590
173 + 26417 = 26590
191 + 26399 = 26590

Showing the first eight; more decompositions exist.
