Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610642, here are decompositions:

41 + 8610601 = 8610642
43 + 8610599 = 8610642
59 + 8610583 = 8610642
83 + 8610559 = 8610642
163 + 8610479 = 8610642
179 + 8610463 = 8610642
181 + 8610461 = 8610642
199 + 8610443 = 8610642

Showing the first eight; more decompositions exist.
