Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987700, here are decompositions:

3 + 987697 = 987700
41 + 987659 = 987700
101 + 987599 = 987700
107 + 987593 = 987700
113 + 987587 = 987700
167 + 987533 = 987700
191 + 987509 = 987700
227 + 987473 = 987700

Showing the first eight; more decompositions exist.
