Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987706, here are decompositions:

47 + 987659 = 987706
107 + 987599 = 987706
113 + 987593 = 987706
173 + 987533 = 987706
197 + 987509 = 987706
233 + 987473 = 987706
353 + 987353 = 987706
479 + 987227 = 987706

Showing the first eight; more decompositions exist.
