Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167690, here are decompositions:

7 + 167683 = 167690
13 + 167677 = 167690
67 + 167623 = 167690
79 + 167611 = 167690
97 + 167593 = 167690
199 + 167491 = 167690
241 + 167449 = 167690
277 + 167413 = 167690

Showing the first eight; more decompositions exist.
