Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15154, here are decompositions:

5 + 15149 = 15154
17 + 15137 = 15154
23 + 15131 = 15154
47 + 15107 = 15154
53 + 15101 = 15154
71 + 15083 = 15154
101 + 15053 = 15154
137 + 15017 = 15154

Showing the first eight; more decompositions exist.
