Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710642, here are decompositions:

11 + 8710631 = 8710642
53 + 8710589 = 8710642
71 + 8710571 = 8710642
113 + 8710529 = 8710642
389 + 8710253 = 8710642
401 + 8710241 = 8710642
449 + 8710193 = 8710642
599 + 8710043 = 8710642

Showing the first eight; more decompositions exist.
