Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26390, here are decompositions:

3 + 26387 = 26390
19 + 26371 = 26390
43 + 26347 = 26390
73 + 26317 = 26390
97 + 26293 = 26390
127 + 26263 = 26390
139 + 26251 = 26390
163 + 26227 = 26390

Showing the first eight; more decompositions exist.
