Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167490, here are decompositions:

7 + 167483 = 167490
19 + 167471 = 167490
41 + 167449 = 167490
47 + 167443 = 167490
53 + 167437 = 167490
61 + 167429 = 167490
67 + 167423 = 167490
83 + 167407 = 167490

Showing the first eight; more decompositions exist.
