Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105084, here are decompositions:

13 + 105071 = 105084
47 + 105037 = 105084
53 + 105031 = 105084
61 + 105023 = 105084
97 + 104987 = 105084
113 + 104971 = 105084
131 + 104953 = 105084
137 + 104947 = 105084

Showing the first eight; more decompositions exist.
