Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102546, here are decompositions:

7 + 102539 = 102546
13 + 102533 = 102546
23 + 102523 = 102546
43 + 102503 = 102546
47 + 102499 = 102546
109 + 102437 = 102546
113 + 102433 = 102546
137 + 102409 = 102546

Showing the first eight; more decompositions exist.
