Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101172, here are decompositions:

11 + 101161 = 101172
13 + 101159 = 101172
23 + 101149 = 101172
31 + 101141 = 101172
53 + 101119 = 101172
59 + 101113 = 101172
61 + 101111 = 101172
83 + 101089 = 101172

Showing the first eight; more decompositions exist.
