Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123554, here are decompositions:

3 + 123551 = 123554
7 + 123547 = 123554
37 + 123517 = 123554
61 + 123493 = 123554
97 + 123457 = 123554
127 + 123427 = 123554
157 + 123397 = 123554
181 + 123373 = 123554

Showing the first eight; more decompositions exist.
