Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018842, here are decompositions:

29 + 1018813 = 1018842
31 + 1018811 = 1018842
53 + 1018789 = 1018842
73 + 1018769 = 1018842
79 + 1018763 = 1018842
109 + 1018733 = 1018842
113 + 1018729 = 1018842
131 + 1018711 = 1018842

Showing the first eight; more decompositions exist.
