Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987472, here are decompositions:

89 + 987383 = 987472
173 + 987299 = 987472
179 + 987293 = 987472
263 + 987209 = 987472
281 + 987191 = 987472
383 + 987089 = 987472
389 + 987083 = 987472
419 + 987053 = 987472

Showing the first eight; more decompositions exist.
