Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563840, here are decompositions:

3 + 563837 = 563840
19 + 563821 = 563840
31 + 563809 = 563840
97 + 563743 = 563840
241 + 563599 = 563840
337 + 563503 = 563840
373 + 563467 = 563840
421 + 563419 = 563840

Showing the first eight; more decompositions exist.
