Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125478, here are decompositions:

7 + 125471 = 125478
37 + 125441 = 125478
71 + 125407 = 125478
79 + 125399 = 125478
107 + 125371 = 125478
139 + 125339 = 125478
149 + 125329 = 125478
167 + 125311 = 125478

Showing the first eight; more decompositions exist.
