Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003842, here are decompositions:

23 + 1003819 = 1003842
71 + 1003771 = 1003842
79 + 1003763 = 1003842
89 + 1003753 = 1003842
101 + 1003741 = 1003842
109 + 1003733 = 1003842
113 + 1003729 = 1003842
131 + 1003711 = 1003842

Showing the first eight; more decompositions exist.
