Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731456, here are decompositions:

23 + 8731433 = 8731456
29 + 8731427 = 8731456
113 + 8731343 = 8731456
179 + 8731277 = 8731456
269 + 8731187 = 8731456
317 + 8731139 = 8731456
347 + 8731109 = 8731456
353 + 8731103 = 8731456

Showing the first eight; more decompositions exist.
