Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102520, here are decompositions:

17 + 102503 = 102520
23 + 102497 = 102520
59 + 102461 = 102520
83 + 102437 = 102520
113 + 102407 = 102520
191 + 102329 = 102520
227 + 102293 = 102520
269 + 102251 = 102520

Showing the first eight; more decompositions exist.
