Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561146, here are decompositions:

37 + 561109 = 561146
43 + 561103 = 561146
67 + 561079 = 561146
127 + 561019 = 561146
277 + 560869 = 561146
283 + 560863 = 561146
349 + 560797 = 561146
379 + 560767 = 561146

Showing the first eight; more decompositions exist.
