Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987612, here are decompositions:

5 + 987607 = 987612
13 + 987599 = 987612
19 + 987593 = 987612
53 + 987559 = 987612
71 + 987541 = 987612
79 + 987533 = 987612
89 + 987523 = 987612
103 + 987509 = 987612

Showing the first eight; more decompositions exist.
