Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515684, here are decompositions:

3 + 515681 = 515684
7 + 515677 = 515684
31 + 515653 = 515684
73 + 515611 = 515684
97 + 515587 = 515684
283 + 515401 = 515684
307 + 515377 = 515684
313 + 515371 = 515684

Showing the first eight; more decompositions exist.
