Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15100, here are decompositions:

17 + 15083 = 15100
23 + 15077 = 15100
47 + 15053 = 15100
83 + 15017 = 15100
131 + 14969 = 15100
149 + 14951 = 15100
233 + 14867 = 15100
257 + 14843 = 15100

Showing the first eight; more decompositions exist.
