Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987248, here are decompositions:

37 + 987211 = 987248
151 + 987097 = 987248
181 + 987067 = 987248
307 + 986941 = 987248
397 + 986851 = 987248
499 + 986749 = 987248
541 + 986707 = 987248
607 + 986641 = 987248

Showing the first eight; more decompositions exist.
