Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987742, here are decompositions:

3 + 987739 = 987742
29 + 987713 = 987742
83 + 987659 = 987742
149 + 987593 = 987742
233 + 987509 = 987742
251 + 987491 = 987742
269 + 987473 = 987742
359 + 987383 = 987742

Showing the first eight; more decompositions exist.
