Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018394, here are decompositions:

37 + 1018357 = 1018394
103 + 1018291 = 1018394
193 + 1018201 = 1018394
271 + 1018123 = 1018394
337 + 1018057 = 1018394
373 + 1018021 = 1018394
397 + 1017997 = 1018394
547 + 1017847 = 1018394

Showing the first eight; more decompositions exist.
