Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018370, here are decompositions:

13 + 1018357 = 1018370
61 + 1018309 = 1018370
79 + 1018291 = 1018370
163 + 1018207 = 1018370
193 + 1018177 = 1018370
313 + 1018057 = 1018370
349 + 1018021 = 1018370
373 + 1017997 = 1018370

Showing the first eight; more decompositions exist.
