Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564840, here are decompositions:

13 + 564827 = 564840
43 + 564797 = 564840
47 + 564793 = 564840
61 + 564779 = 564840
79 + 564761 = 564840
127 + 564713 = 564840
131 + 564709 = 564840
137 + 564703 = 564840

Showing the first eight; more decompositions exist.
