Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710990, here are decompositions:

11 + 8710979 = 8710990
17 + 8710973 = 8710990
23 + 8710967 = 8710990
257 + 8710733 = 8710990
263 + 8710727 = 8710990
311 + 8710679 = 8710990
359 + 8710631 = 8710990
401 + 8710589 = 8710990

Showing the first eight; more decompositions exist.
