Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8754990, here are decompositions:

11 + 8754979 = 8754990
19 + 8754971 = 8754990
31 + 8754959 = 8754990
59 + 8754931 = 8754990
71 + 8754919 = 8754990
73 + 8754917 = 8754990
107 + 8754883 = 8754990
239 + 8754751 = 8754990

Showing the first eight; more decompositions exist.
