Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72510, here are decompositions:

7 + 72503 = 72510
13 + 72497 = 72510
17 + 72493 = 72510
29 + 72481 = 72510
41 + 72469 = 72510
43 + 72467 = 72510
79 + 72431 = 72510
89 + 72421 = 72510

Showing the first eight; more decompositions exist.
