Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742898, here are decompositions:

11 + 8742887 = 8742898
41 + 8742857 = 8742898
347 + 8742551 = 8742898
401 + 8742497 = 8742898
449 + 8742449 = 8742898
701 + 8742197 = 8742898
821 + 8742077 = 8742898
839 + 8742059 = 8742898

Showing the first eight; more decompositions exist.
