Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644694, here are decompositions:

43 + 8644651 = 8644694
61 + 8644633 = 8644694
193 + 8644501 = 8644694
241 + 8644453 = 8644694
367 + 8644327 = 8644694
433 + 8644261 = 8644694
463 + 8644231 = 8644694
523 + 8644171 = 8644694

Showing the first eight; more decompositions exist.
