Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019842, here are decompositions:

3 + 1019839 = 1019842
23 + 1019819 = 1019842
41 + 1019801 = 1019842
59 + 1019783 = 1019842
71 + 1019771 = 1019842
101 + 1019741 = 1019842
113 + 1019729 = 1019842
149 + 1019693 = 1019842

Showing the first eight; more decompositions exist.
