Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105098, here are decompositions:

61 + 105037 = 105098
67 + 105031 = 105098
79 + 105019 = 105098
127 + 104971 = 105098
139 + 104959 = 105098
151 + 104947 = 105098
181 + 104917 = 105098
229 + 104869 = 105098

Showing the first eight; more decompositions exist.
