Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987554, here are decompositions:

13 + 987541 = 987554
31 + 987523 = 987554
97 + 987457 = 987554
163 + 987391 = 987554
193 + 987361 = 987554
241 + 987313 = 987554
457 + 987097 = 987554
487 + 987067 = 987554

Showing the first eight; more decompositions exist.
