Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644544, here are decompositions:

37 + 8644507 = 8644544
43 + 8644501 = 8644544
67 + 8644477 = 8644544
283 + 8644261 = 8644544
313 + 8644231 = 8644544
331 + 8644213 = 8644544
373 + 8644171 = 8644544
397 + 8644147 = 8644544

Showing the first eight; more decompositions exist.
