Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121554, here are decompositions:

7 + 121547 = 121554
23 + 121531 = 121554
31 + 121523 = 121554
47 + 121507 = 121554
53 + 121501 = 121554
61 + 121493 = 121554
67 + 121487 = 121554
101 + 121453 = 121554

Showing the first eight; more decompositions exist.
