Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003856, here are decompositions:

37 + 1003819 = 1003856
103 + 1003753 = 1003856
109 + 1003747 = 1003856
127 + 1003729 = 1003856
163 + 1003693 = 1003856
229 + 1003627 = 1003856
307 + 1003549 = 1003856
313 + 1003543 = 1003856

Showing the first eight; more decompositions exist.
