Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561494, here are decompositions:

127 + 561367 = 561494
151 + 561343 = 561494
181 + 561313 = 561494
313 + 561181 = 561494
397 + 561097 = 561494
433 + 561061 = 561494
601 + 560893 = 561494
607 + 560887 = 561494

Showing the first eight; more decompositions exist.
