Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2530, here are decompositions:

53 + 2477 = 2530
71 + 2459 = 2530
83 + 2447 = 2530
89 + 2441 = 2530
107 + 2423 = 2530
113 + 2417 = 2530
131 + 2399 = 2530
137 + 2393 = 2530

Showing the first eight; more decompositions exist.
