Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987284, here are decompositions:

73 + 987211 = 987284
157 + 987127 = 987284
223 + 987061 = 987284
241 + 987043 = 987284
271 + 987013 = 987284
433 + 986851 = 987284
547 + 986737 = 987284
577 + 986707 = 987284

Showing the first eight; more decompositions exist.
