Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2544, here are decompositions:

5 + 2539 = 2544
13 + 2531 = 2544
23 + 2521 = 2544
41 + 2503 = 2544
67 + 2477 = 2544
71 + 2473 = 2544
97 + 2447 = 2544
103 + 2441 = 2544

Showing the first eight; more decompositions exist.
