Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731558, here are decompositions:

29 + 8731529 = 8731558
47 + 8731511 = 8731558
131 + 8731427 = 8731558
257 + 8731301 = 8731558
281 + 8731277 = 8731558
347 + 8731211 = 8731558
419 + 8731139 = 8731558
449 + 8731109 = 8731558

Showing the first eight; more decompositions exist.
