Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18524, here are decompositions:

3 + 18521 = 18524
7 + 18517 = 18524
31 + 18493 = 18524
43 + 18481 = 18524
67 + 18457 = 18524
73 + 18451 = 18524
97 + 18427 = 18524
127 + 18397 = 18524

Showing the first eight; more decompositions exist.
