Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123508, here are decompositions:

5 + 123503 = 123508
17 + 123491 = 123508
29 + 123479 = 123508
59 + 123449 = 123508
89 + 123419 = 123508
101 + 123407 = 123508
107 + 123401 = 123508
131 + 123377 = 123508

Showing the first eight; more decompositions exist.
