Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727428, here are decompositions:

79 + 8727349 = 8727428
181 + 8727247 = 8727428
271 + 8727157 = 8727428
337 + 8727091 = 8727428
379 + 8727049 = 8727428
397 + 8727031 = 8727428
439 + 8726989 = 8727428
691 + 8726737 = 8727428

Showing the first eight; more decompositions exist.
