Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515654, here are decompositions:

3 + 515651 = 515654
43 + 515611 = 515654
67 + 515587 = 515654
277 + 515377 = 515654
283 + 515371 = 515654
331 + 515323 = 515654
421 + 515233 = 515654
463 + 515191 = 515654

Showing the first eight; more decompositions exist.
