Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7526, here are decompositions:

3 + 7523 = 7526
19 + 7507 = 7526
37 + 7489 = 7526
67 + 7459 = 7526
109 + 7417 = 7526
157 + 7369 = 7526
193 + 7333 = 7526
229 + 7297 = 7526

Showing the first eight; more decompositions exist.
