Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28436, here are decompositions:

3 + 28433 = 28436
7 + 28429 = 28436
43 + 28393 = 28436
127 + 28309 = 28436
139 + 28297 = 28436
157 + 28279 = 28436
313 + 28123 = 28436
337 + 28099 = 28436

Showing the first eight; more decompositions exist.
