Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018498, here are decompositions:

59 + 1018439 = 1018498
197 + 1018301 = 1018498
227 + 1018271 = 1018498
251 + 1018247 = 1018498
281 + 1018217 = 1018498
389 + 1018109 = 1018498
401 + 1018097 = 1018498
479 + 1018019 = 1018498

Showing the first eight; more decompositions exist.
