Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15862, here are decompositions:

3 + 15859 = 15862
53 + 15809 = 15862
59 + 15803 = 15862
71 + 15791 = 15862
89 + 15773 = 15862
101 + 15761 = 15862
113 + 15749 = 15862
131 + 15731 = 15862

Showing the first eight; more decompositions exist.
