Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28606, here are decompositions:

3 + 28603 = 28606
47 + 28559 = 28606
59 + 28547 = 28606
89 + 28517 = 28606
107 + 28499 = 28606
113 + 28493 = 28606
167 + 28439 = 28606
173 + 28433 = 28606

Showing the first eight; more decompositions exist.
