Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987564, here are decompositions:

5 + 987559 = 987564
23 + 987541 = 987564
31 + 987533 = 987564
41 + 987523 = 987564
73 + 987491 = 987564
101 + 987463 = 987564
107 + 987457 = 987564
131 + 987433 = 987564

Showing the first eight; more decompositions exist.
