Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40170, here are decompositions:

7 + 40163 = 40170
17 + 40153 = 40170
19 + 40151 = 40170
41 + 40129 = 40170
43 + 40127 = 40170
47 + 40123 = 40170
59 + 40111 = 40170
71 + 40099 = 40170

Showing the first eight; more decompositions exist.
