Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727490, here are decompositions:

59 + 8727431 = 8727490
131 + 8727359 = 8727490
173 + 8727317 = 8727490
227 + 8727263 = 8727490
293 + 8727197 = 8727490
311 + 8727179 = 8727490
503 + 8726987 = 8727490
521 + 8726969 = 8727490

Showing the first eight; more decompositions exist.
