Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644202, here are decompositions:

31 + 8644171 = 8644202
79 + 8644123 = 8644202
211 + 8643991 = 8644202
283 + 8643919 = 8644202
313 + 8643889 = 8644202
571 + 8643631 = 8644202
613 + 8643589 = 8644202
769 + 8643433 = 8644202

Showing the first eight; more decompositions exist.
