Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744900, here are decompositions:

13 + 8744887 = 8744900
67 + 8744833 = 8744900
163 + 8744737 = 8744900
193 + 8744707 = 8744900
337 + 8744563 = 8744900
349 + 8744551 = 8744900
433 + 8744467 = 8744900
487 + 8744413 = 8744900

Showing the first eight; more decompositions exist.
