Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105478, here are decompositions:

11 + 105467 = 105478
29 + 105449 = 105478
41 + 105437 = 105478
71 + 105407 = 105478
89 + 105389 = 105478
137 + 105341 = 105478
227 + 105251 = 105478
239 + 105239 = 105478

Showing the first eight; more decompositions exist.
