Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987356, here are decompositions:

3 + 987353 = 987356
43 + 987313 = 987356
157 + 987199 = 987356
163 + 987193 = 987356
229 + 987127 = 987356
277 + 987079 = 987356
313 + 987043 = 987356
367 + 986989 = 987356

Showing the first eight; more decompositions exist.
