Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640374, here are decompositions:

37 + 8640337 = 8640374
163 + 8640211 = 8640374
241 + 8640133 = 8640374
373 + 8640001 = 8640374
397 + 8639977 = 8640374
571 + 8639803 = 8640374
577 + 8639797 = 8640374
601 + 8639773 = 8640374

Showing the first eight; more decompositions exist.
