Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126188, here are decompositions:

37 + 126151 = 126188
61 + 126127 = 126188
109 + 126079 = 126188
151 + 126037 = 126188
157 + 126031 = 126188
229 + 125959 = 126188
367 + 125821 = 126188
397 + 125791 = 126188

Showing the first eight; more decompositions exist.
