Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102644, here are decompositions:

37 + 102607 = 102644
97 + 102547 = 102644
163 + 102481 = 102644
193 + 102451 = 102644
211 + 102433 = 102644
277 + 102367 = 102644
307 + 102337 = 102644
463 + 102181 = 102644

Showing the first eight; more decompositions exist.
