Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018072, here are decompositions:

53 + 1018019 = 1018072
113 + 1017959 = 1018072
149 + 1017923 = 1018072
191 + 1017881 = 1018072
353 + 1017719 = 1018072
359 + 1017713 = 1018072
389 + 1017683 = 1018072
449 + 1017623 = 1018072

Showing the first eight; more decompositions exist.
