Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167538, here are decompositions:

17 + 167521 = 167538
47 + 167491 = 167538
67 + 167471 = 167538
89 + 167449 = 167538
97 + 167441 = 167538
101 + 167437 = 167538
109 + 167429 = 167538
131 + 167407 = 167538

Showing the first eight; more decompositions exist.
