Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564642, here are decompositions:

109 + 564533 = 564642
151 + 564491 = 564642
179 + 564463 = 564642
193 + 564449 = 564642
223 + 564419 = 564642
233 + 564409 = 564642
241 + 564401 = 564642
251 + 564391 = 564642

Showing the first eight; more decompositions exist.
