Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749900, here are decompositions:

53 + 8749847 = 8749900
59 + 8749841 = 8749900
83 + 8749817 = 8749900
113 + 8749787 = 8749900
149 + 8749751 = 8749900
167 + 8749733 = 8749900
293 + 8749607 = 8749900
311 + 8749589 = 8749900

Showing the first eight; more decompositions exist.
