Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987956, here are decompositions:

43 + 987913 = 987956
163 + 987793 = 987956
349 + 987607 = 987956
397 + 987559 = 987956
433 + 987523 = 987956
499 + 987457 = 987956
523 + 987433 = 987956
643 + 987313 = 987956

Showing the first eight; more decompositions exist.
