Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719380, here are decompositions:

13 + 8719367 = 8719380
31 + 8719349 = 8719380
53 + 8719327 = 8719380
73 + 8719307 = 8719380
79 + 8719301 = 8719380
107 + 8719273 = 8719380
127 + 8719253 = 8719380
157 + 8719223 = 8719380

Showing the first eight; more decompositions exist.
