Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731630, here are decompositions:

3 + 8731627 = 8731630
23 + 8731607 = 8731630
59 + 8731571 = 8731630
101 + 8731529 = 8731630
137 + 8731493 = 8731630
197 + 8731433 = 8731630
317 + 8731313 = 8731630
353 + 8731277 = 8731630

Showing the first eight; more decompositions exist.
