Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15180, here are decompositions:

7 + 15173 = 15180
19 + 15161 = 15180
31 + 15149 = 15180
41 + 15139 = 15180
43 + 15137 = 15180
59 + 15121 = 15180
73 + 15107 = 15180
79 + 15101 = 15180

Showing the first eight; more decompositions exist.
