Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018160, here are decompositions:

37 + 1018123 = 1018160
103 + 1018057 = 1018160
139 + 1018021 = 1018160
163 + 1017997 = 1018160
271 + 1017889 = 1018160
313 + 1017847 = 1018160
373 + 1017787 = 1018160
379 + 1017781 = 1018160

Showing the first eight; more decompositions exist.
