Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018538, here are decompositions:

61 + 1018477 = 1018538
67 + 1018471 = 1018538
109 + 1018429 = 1018538
127 + 1018411 = 1018538
181 + 1018357 = 1018538
229 + 1018309 = 1018538
331 + 1018207 = 1018538
337 + 1018201 = 1018538

Showing the first eight; more decompositions exist.
