Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190308, here are decompositions:

7 + 190301 = 190308
11 + 190297 = 190308
37 + 190271 = 190308
47 + 190261 = 190308
59 + 190249 = 190308
101 + 190207 = 190308
127 + 190181 = 190308
149 + 190159 = 190308

Showing the first eight; more decompositions exist.
