Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156564, here are decompositions:

43 + 156521 = 156564
53 + 156511 = 156564
71 + 156493 = 156564
73 + 156491 = 156564
97 + 156467 = 156564
127 + 156437 = 156564
193 + 156371 = 156564
211 + 156353 = 156564

Showing the first eight; more decompositions exist.
