Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018308, here are decompositions:

7 + 1018301 = 1018308
17 + 1018291 = 1018308
37 + 1018271 = 1018308
61 + 1018247 = 1018308
101 + 1018207 = 1018308
107 + 1018201 = 1018308
131 + 1018177 = 1018308
199 + 1018109 = 1018308

Showing the first eight; more decompositions exist.
