Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105698, here are decompositions:

7 + 105691 = 105698
31 + 105667 = 105698
79 + 105619 = 105698
97 + 105601 = 105698
157 + 105541 = 105698
181 + 105517 = 105698
199 + 105499 = 105698
331 + 105367 = 105698

Showing the first eight; more decompositions exist.
