Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140172, here are decompositions:

5 + 140167 = 140172
13 + 140159 = 140172
29 + 140143 = 140172
61 + 140111 = 140172
101 + 140071 = 140172
103 + 140069 = 140172
163 + 140009 = 140172
173 + 139999 = 140172

Showing the first eight; more decompositions exist.
