Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130406, here are decompositions:

7 + 130399 = 130406
37 + 130369 = 130406
43 + 130363 = 130406
103 + 130303 = 130406
127 + 130279 = 130406
139 + 130267 = 130406
223 + 130183 = 130406
307 + 130099 = 130406

Showing the first eight; more decompositions exist.
