Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987726, here are decompositions:

13 + 987713 = 987726
29 + 987697 = 987726
67 + 987659 = 987726
127 + 987599 = 987726
139 + 987587 = 987726
167 + 987559 = 987726
193 + 987533 = 987726
263 + 987463 = 987726

Showing the first eight; more decompositions exist.
