Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105494, here are decompositions:

3 + 105491 = 105494
97 + 105397 = 105494
127 + 105367 = 105494
157 + 105337 = 105494
163 + 105331 = 105494
241 + 105253 = 105494
283 + 105211 = 105494
397 + 105097 = 105494

Showing the first eight; more decompositions exist.
