Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705942, here are decompositions:

19 + 8705923 = 8705942
31 + 8705911 = 8705942
61 + 8705881 = 8705942
139 + 8705803 = 8705942
151 + 8705791 = 8705942
331 + 8705611 = 8705942
499 + 8705443 = 8705942
523 + 8705419 = 8705942

Showing the first eight; more decompositions exist.
