Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018148, here are decompositions:

127 + 1018021 = 1018148
151 + 1017997 = 1018148
331 + 1017817 = 1018148
349 + 1017799 = 1018148
367 + 1017781 = 1018148
499 + 1017649 = 1018148
541 + 1017607 = 1018148
709 + 1017439 = 1018148

Showing the first eight; more decompositions exist.
