Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156582, here are decompositions:

5 + 156577 = 156582
43 + 156539 = 156582
61 + 156521 = 156582
71 + 156511 = 156582
89 + 156493 = 156582
163 + 156419 = 156582
211 + 156371 = 156582
229 + 156353 = 156582

Showing the first eight; more decompositions exist.
