Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105454, here are decompositions:

5 + 105449 = 105454
17 + 105437 = 105454
47 + 105407 = 105454
53 + 105401 = 105454
113 + 105341 = 105454
131 + 105323 = 105454
191 + 105263 = 105454
227 + 105227 = 105454

Showing the first eight; more decompositions exist.
