Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126458, here are decompositions:

37 + 126421 = 126458
61 + 126397 = 126458
109 + 126349 = 126458
151 + 126307 = 126458
229 + 126229 = 126458
307 + 126151 = 126458
331 + 126127 = 126458
379 + 126079 = 126458

Showing the first eight; more decompositions exist.
