Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613724, here are decompositions:

23 + 8613701 = 8613724
47 + 8613677 = 8613724
101 + 8613623 = 8613724
107 + 8613617 = 8613724
263 + 8613461 = 8613724
401 + 8613323 = 8613724
443 + 8613281 = 8613724
503 + 8613221 = 8613724

Showing the first eight; more decompositions exist.
