Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987732, here are decompositions:

19 + 987713 = 987732
73 + 987659 = 987732
101 + 987631 = 987732
139 + 987593 = 987732
173 + 987559 = 987732
191 + 987541 = 987732
199 + 987533 = 987732
223 + 987509 = 987732

Showing the first eight; more decompositions exist.
