Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28412, here are decompositions:

3 + 28409 = 28412
19 + 28393 = 28412
61 + 28351 = 28412
103 + 28309 = 28412
193 + 28219 = 28412
211 + 28201 = 28412
229 + 28183 = 28412
313 + 28099 = 28412

Showing the first eight; more decompositions exist.
