Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169130, here are decompositions:

19 + 169111 = 169130
37 + 169093 = 169130
61 + 169069 = 169130
67 + 169063 = 169130
127 + 169003 = 169130
139 + 168991 = 169130
193 + 168937 = 169130
229 + 168901 = 169130

Showing the first eight; more decompositions exist.
