Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727380, here are decompositions:

31 + 8727349 = 8727380
37 + 8727343 = 8727380
97 + 8727283 = 8727380
223 + 8727157 = 8727380
271 + 8727109 = 8727380
313 + 8727067 = 8727380
331 + 8727049 = 8727380
349 + 8727031 = 8727380

Showing the first eight; more decompositions exist.
