Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987574, here are decompositions:

41 + 987533 = 987574
83 + 987491 = 987574
101 + 987473 = 987574
191 + 987383 = 987574
281 + 987293 = 987574
347 + 987227 = 987574
383 + 987191 = 987574
431 + 987143 = 987574

Showing the first eight; more decompositions exist.
