Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105972, here are decompositions:

5 + 105967 = 105972
19 + 105953 = 105972
29 + 105943 = 105972
43 + 105929 = 105972
59 + 105913 = 105972
73 + 105899 = 105972
89 + 105883 = 105972
101 + 105871 = 105972

Showing the first eight; more decompositions exist.
