Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15144, here are decompositions:

5 + 15139 = 15144
7 + 15137 = 15144
13 + 15131 = 15144
23 + 15121 = 15144
37 + 15107 = 15144
43 + 15101 = 15144
53 + 15091 = 15144
61 + 15083 = 15144

Showing the first eight; more decompositions exist.
