Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731624, here are decompositions:

17 + 8731607 = 8731624
53 + 8731571 = 8731624
113 + 8731511 = 8731624
131 + 8731493 = 8731624
191 + 8731433 = 8731624
197 + 8731427 = 8731624
281 + 8731343 = 8731624
311 + 8731313 = 8731624

Showing the first eight; more decompositions exist.
