Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731648, here are decompositions:

5 + 8731643 = 8731648
11 + 8731637 = 8731648
41 + 8731607 = 8731648
137 + 8731511 = 8731648
347 + 8731301 = 8731648
461 + 8731187 = 8731648
509 + 8731139 = 8731648
617 + 8731031 = 8731648

Showing the first eight; more decompositions exist.
