Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987738, here are decompositions:

41 + 987697 = 987738
79 + 987659 = 987738
107 + 987631 = 987738
131 + 987607 = 987738
139 + 987599 = 987738
151 + 987587 = 987738
179 + 987559 = 987738
197 + 987541 = 987738

Showing the first eight; more decompositions exist.
