Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130370, here are decompositions:

3 + 130367 = 130370
7 + 130363 = 130370
67 + 130303 = 130370
103 + 130267 = 130370
109 + 130261 = 130370
199 + 130171 = 130370
223 + 130147 = 130370
271 + 130099 = 130370

Showing the first eight; more decompositions exist.
