Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938900, here are decompositions:

19 + 938881 = 938900
31 + 938869 = 938900
43 + 938857 = 938900
73 + 938827 = 938900
97 + 938803 = 938900
139 + 938761 = 938900
223 + 938677 = 938900
241 + 938659 = 938900

Showing the first eight; more decompositions exist.
