Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731546, here are decompositions:

17 + 8731529 = 8731546
53 + 8731493 = 8731546
113 + 8731433 = 8731546
233 + 8731313 = 8731546
269 + 8731277 = 8731546
359 + 8731187 = 8731546
443 + 8731103 = 8731546
449 + 8731097 = 8731546

Showing the first eight; more decompositions exist.
