Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731600, here are decompositions:

29 + 8731571 = 8731600
71 + 8731529 = 8731600
89 + 8731511 = 8731600
107 + 8731493 = 8731600
167 + 8731433 = 8731600
173 + 8731427 = 8731600
257 + 8731343 = 8731600
389 + 8731211 = 8731600

Showing the first eight; more decompositions exist.
