Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11582, here are decompositions:

3 + 11579 = 11582
31 + 11551 = 11582
79 + 11503 = 11582
139 + 11443 = 11582
199 + 11383 = 11582
229 + 11353 = 11582
271 + 11311 = 11582
283 + 11299 = 11582

Showing the first eight; more decompositions exist.
