Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719900, here are decompositions:

53 + 8719847 = 8719900
83 + 8719817 = 8719900
197 + 8719703 = 8719900
239 + 8719661 = 8719900
359 + 8719541 = 8719900
479 + 8719421 = 8719900
509 + 8719391 = 8719900
521 + 8719379 = 8719900

Showing the first eight; more decompositions exist.
