Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162530, here are decompositions:

3 + 162527 = 162530
7 + 162523 = 162530
13 + 162517 = 162530
31 + 162499 = 162530
37 + 162493 = 162530
73 + 162457 = 162530
79 + 162451 = 162530
139 + 162391 = 162530

Showing the first eight; more decompositions exist.
