Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513146, here are decompositions:

37 + 513109 = 513146
43 + 513103 = 513146
79 + 513067 = 513146
157 + 512989 = 513146
229 + 512917 = 513146
349 + 512797 = 513146
367 + 512779 = 513146
379 + 512767 = 513146

Showing the first eight; more decompositions exist.
