Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018608, here are decompositions:

131 + 1018477 = 1018608
137 + 1018471 = 1018608
179 + 1018429 = 1018608
197 + 1018411 = 1018608
251 + 1018357 = 1018608
271 + 1018337 = 1018608
307 + 1018301 = 1018608
317 + 1018291 = 1018608

Showing the first eight; more decompositions exist.
