Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002278, here are decompositions:

19 + 1002259 = 1002278
31 + 1002247 = 1002278
37 + 1002241 = 1002278
127 + 1002151 = 1002278
157 + 1002121 = 1002278
229 + 1002049 = 1002278
331 + 1001947 = 1002278
337 + 1001941 = 1002278

Showing the first eight; more decompositions exist.
