Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15954, here are decompositions:

17 + 15937 = 15954
31 + 15923 = 15954
41 + 15913 = 15954
47 + 15907 = 15954
53 + 15901 = 15954
67 + 15887 = 15954
73 + 15881 = 15954
131 + 15823 = 15954

Showing the first eight; more decompositions exist.
