Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561506, here are decompositions:

67 + 561439 = 561506
97 + 561409 = 561506
139 + 561367 = 561506
163 + 561343 = 561506
193 + 561313 = 561506
199 + 561307 = 561506
229 + 561277 = 561506
277 + 561229 = 561506

Showing the first eight; more decompositions exist.
