Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7544, here are decompositions:

3 + 7541 = 7544
7 + 7537 = 7544
37 + 7507 = 7544
67 + 7477 = 7544
127 + 7417 = 7544
151 + 7393 = 7544
193 + 7351 = 7544
211 + 7333 = 7544

Showing the first eight; more decompositions exist.
