Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013900, here are decompositions:

7 + 1013893 = 1013900
61 + 1013839 = 1013900
67 + 1013833 = 1013900
73 + 1013827 = 1013900
109 + 1013791 = 1013900
127 + 1013773 = 1013900
229 + 1013671 = 1013900
271 + 1013629 = 1013900

Showing the first eight; more decompositions exist.
