Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687554, here are decompositions:

41 + 8687513 = 8687554
101 + 8687453 = 8687554
131 + 8687423 = 8687554
167 + 8687387 = 8687554
173 + 8687381 = 8687554
191 + 8687363 = 8687554
233 + 8687321 = 8687554
251 + 8687303 = 8687554

Showing the first eight; more decompositions exist.
