Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987282, here are decompositions:

31 + 987251 = 987282
71 + 987211 = 987282
73 + 987209 = 987282
83 + 987199 = 987282
89 + 987193 = 987282
139 + 987143 = 987282
181 + 987101 = 987282
193 + 987089 = 987282

Showing the first eight; more decompositions exist.
