Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123576, here are decompositions:

23 + 123553 = 123576
29 + 123547 = 123576
59 + 123517 = 123576
73 + 123503 = 123576
83 + 123493 = 123576
97 + 123479 = 123576
127 + 123449 = 123576
137 + 123439 = 123576

Showing the first eight; more decompositions exist.
