Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727408, here are decompositions:

59 + 8727349 = 8727408
139 + 8727269 = 8727408
197 + 8727211 = 8727408
211 + 8727197 = 8727408
229 + 8727179 = 8727408
251 + 8727157 = 8727408
317 + 8727091 = 8727408
359 + 8727049 = 8727408

Showing the first eight; more decompositions exist.
