Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003900, here are decompositions:

3 + 1003897 = 1003900
11 + 1003889 = 1003900
59 + 1003841 = 1003900
83 + 1003817 = 1003900
113 + 1003787 = 1003900
137 + 1003763 = 1003900
167 + 1003733 = 1003900
269 + 1003631 = 1003900

Showing the first eight; more decompositions exist.
