Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171144, here are decompositions:

13 + 171131 = 171144
41 + 171103 = 171144
53 + 171091 = 171144
67 + 171077 = 171144
97 + 171047 = 171144
101 + 171043 = 171144
137 + 171007 = 171144
173 + 170971 = 171144

Showing the first eight; more decompositions exist.
