Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610644, here are decompositions:

37 + 8610607 = 8610644
43 + 8610601 = 8610644
61 + 8610583 = 8610644
181 + 8610463 = 8610644
241 + 8610403 = 8610644
271 + 8610373 = 8610644
277 + 8610367 = 8610644
313 + 8610331 = 8610644

Showing the first eight; more decompositions exist.
