Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15534, here are decompositions:

7 + 15527 = 15534
23 + 15511 = 15534
37 + 15497 = 15534
41 + 15493 = 15534
61 + 15473 = 15534
67 + 15467 = 15534
73 + 15461 = 15534
83 + 15451 = 15534

Showing the first eight; more decompositions exist.
