Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126550, here are decompositions:

3 + 126547 = 126550
59 + 126491 = 126550
89 + 126461 = 126550
107 + 126443 = 126550
191 + 126359 = 126550
227 + 126323 = 126550
233 + 126317 = 126550
239 + 126311 = 126550

Showing the first eight; more decompositions exist.
