Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15084, here are decompositions:

7 + 15077 = 15084
11 + 15073 = 15084
23 + 15061 = 15084
31 + 15053 = 15084
53 + 15031 = 15084
67 + 15017 = 15084
71 + 15013 = 15084
101 + 14983 = 15084

Showing the first eight; more decompositions exist.
