Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126580, here are decompositions:

29 + 126551 = 126580
89 + 126491 = 126580
107 + 126473 = 126580
137 + 126443 = 126580
239 + 126341 = 126580
257 + 126323 = 126580
263 + 126317 = 126580
269 + 126311 = 126580

Showing the first eight; more decompositions exist.
