Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15910, here are decompositions:

3 + 15907 = 15910
23 + 15887 = 15910
29 + 15881 = 15910
101 + 15809 = 15910
107 + 15803 = 15910
113 + 15797 = 15910
137 + 15773 = 15910
149 + 15761 = 15910

Showing the first eight; more decompositions exist.
