Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018154, here are decompositions:

31 + 1018123 = 1018154
97 + 1018057 = 1018154
157 + 1017997 = 1018154
307 + 1017847 = 1018154
337 + 1017817 = 1018154
367 + 1017787 = 1018154
373 + 1017781 = 1018154
433 + 1017721 = 1018154

Showing the first eight; more decompositions exist.
