Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561434, here are decompositions:

61 + 561373 = 561434
67 + 561367 = 561434
127 + 561307 = 561434
157 + 561277 = 561434
331 + 561103 = 561434
337 + 561097 = 561434
373 + 561061 = 561434
457 + 560977 = 561434

Showing the first eight; more decompositions exist.
