Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005248, here are decompositions:

7 + 1005241 = 1005248
19 + 1005229 = 1005248
31 + 1005217 = 1005248
61 + 1005187 = 1005248
199 + 1005049 = 1005248
229 + 1005019 = 1005248
241 + 1005007 = 1005248
271 + 1004977 = 1005248

Showing the first eight; more decompositions exist.
