Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125418, here are decompositions:

11 + 125407 = 125418
19 + 125399 = 125418
31 + 125387 = 125418
47 + 125371 = 125418
79 + 125339 = 125418
89 + 125329 = 125418
107 + 125311 = 125418
131 + 125287 = 125418

Showing the first eight; more decompositions exist.
