Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169148, here are decompositions:

19 + 169129 = 169148
37 + 169111 = 169148
79 + 169069 = 169148
139 + 169009 = 169148
157 + 168991 = 169148
211 + 168937 = 169148
367 + 168781 = 169148
379 + 168769 = 169148

Showing the first eight; more decompositions exist.
