Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188454, here are decompositions:

11 + 188443 = 188454
17 + 188437 = 188454
23 + 188431 = 188454
37 + 188417 = 188454
47 + 188407 = 188454
53 + 188401 = 188454
103 + 188351 = 188454
131 + 188323 = 188454

Showing the first eight; more decompositions exist.
