Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727398, here are decompositions:

151 + 8727247 = 8727398
241 + 8727157 = 8727398
307 + 8727091 = 8727398
331 + 8727067 = 8727398
349 + 8727049 = 8727398
367 + 8727031 = 8727398
409 + 8726989 = 8727398
661 + 8726737 = 8727398

Showing the first eight; more decompositions exist.
