Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15140, here are decompositions:

3 + 15137 = 15140
19 + 15121 = 15140
67 + 15073 = 15140
79 + 15061 = 15140
109 + 15031 = 15140
127 + 15013 = 15140
157 + 14983 = 15140
193 + 14947 = 15140

Showing the first eight; more decompositions exist.
