Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171138, here are decompositions:

7 + 171131 = 171138
47 + 171091 = 171138
59 + 171079 = 171138
61 + 171077 = 171138
89 + 171049 = 171138
109 + 171029 = 171138
131 + 171007 = 171138
167 + 170971 = 171138

Showing the first eight; more decompositions exist.
