Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126372, here are decompositions:

13 + 126359 = 126372
23 + 126349 = 126372
31 + 126341 = 126372
61 + 126311 = 126372
101 + 126271 = 126372
131 + 126241 = 126372
139 + 126233 = 126372
149 + 126223 = 126372

Showing the first eight; more decompositions exist.
