Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2510, here are decompositions:

7 + 2503 = 2510
37 + 2473 = 2510
43 + 2467 = 2510
73 + 2437 = 2510
127 + 2383 = 2510
139 + 2371 = 2510
163 + 2347 = 2510
199 + 2311 = 2510

Showing the first eight; more decompositions exist.
