Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987236, here are decompositions:

37 + 987199 = 987236
43 + 987193 = 987236
109 + 987127 = 987236
139 + 987097 = 987236
157 + 987079 = 987236
193 + 987043 = 987236
223 + 987013 = 987236
277 + 986959 = 987236

Showing the first eight; more decompositions exist.
