Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28542, here are decompositions:

5 + 28537 = 28542
29 + 28513 = 28542
43 + 28499 = 28542
79 + 28463 = 28542
103 + 28439 = 28542
109 + 28433 = 28542
113 + 28429 = 28542
131 + 28411 = 28542

Showing the first eight; more decompositions exist.
