Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28514, here are decompositions:

37 + 28477 = 28514
67 + 28447 = 28514
103 + 28411 = 28514
127 + 28387 = 28514
163 + 28351 = 28514
313 + 28201 = 28514
331 + 28183 = 28514
433 + 28081 = 28514

Showing the first eight; more decompositions exist.
