Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167816, here are decompositions:

7 + 167809 = 167816
37 + 167779 = 167816
139 + 167677 = 167816
193 + 167623 = 167816
223 + 167593 = 167816
367 + 167449 = 167816
373 + 167443 = 167816
379 + 167437 = 167816

Showing the first eight; more decompositions exist.
