Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018598, here are decompositions:

109 + 1018489 = 1018598
127 + 1018471 = 1018598
151 + 1018447 = 1018598
241 + 1018357 = 1018598
307 + 1018291 = 1018598
397 + 1018201 = 1018598
421 + 1018177 = 1018598
541 + 1018057 = 1018598

Showing the first eight; more decompositions exist.
