Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731480, here are decompositions:

3 + 8731477 = 8731480
47 + 8731433 = 8731480
53 + 8731427 = 8731480
137 + 8731343 = 8731480
167 + 8731313 = 8731480
179 + 8731301 = 8731480
269 + 8731211 = 8731480
293 + 8731187 = 8731480

Showing the first eight; more decompositions exist.
