Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28670, here are decompositions:

7 + 28663 = 28670
13 + 28657 = 28670
43 + 28627 = 28670
67 + 28603 = 28670
73 + 28597 = 28670
79 + 28591 = 28670
97 + 28573 = 28670
157 + 28513 = 28670

Showing the first eight; more decompositions exist.
