Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987308, here are decompositions:

97 + 987211 = 987308
109 + 987199 = 987308
181 + 987127 = 987308
211 + 987097 = 987308
229 + 987079 = 987308
241 + 987067 = 987308
349 + 986959 = 987308
367 + 986941 = 987308

Showing the first eight; more decompositions exist.
