Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126290, here are decompositions:

19 + 126271 = 126290
61 + 126229 = 126290
67 + 126223 = 126290
79 + 126211 = 126290
139 + 126151 = 126290
163 + 126127 = 126290
193 + 126097 = 126290
211 + 126079 = 126290

Showing the first eight; more decompositions exist.
