Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728282, here are decompositions:

41 + 8728241 = 8728282
71 + 8728211 = 8728282
89 + 8728193 = 8728282
113 + 8728169 = 8728282
293 + 8727989 = 8728282
383 + 8727899 = 8728282
491 + 8727791 = 8728282
503 + 8727779 = 8728282

Showing the first eight; more decompositions exist.
