Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987136, here are decompositions:

47 + 987089 = 987136
53 + 987083 = 987136
83 + 987053 = 987136
107 + 987029 = 987136
113 + 987023 = 987136
173 + 986963 = 987136
233 + 986903 = 987136
317 + 986819 = 987136

Showing the first eight; more decompositions exist.
