Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15126, here are decompositions:

5 + 15121 = 15126
19 + 15107 = 15126
43 + 15083 = 15126
53 + 15073 = 15126
73 + 15053 = 15126
109 + 15017 = 15126
113 + 15013 = 15126
157 + 14969 = 15126

Showing the first eight; more decompositions exist.
