Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158564, here are decompositions:

13 + 158551 = 158564
37 + 158527 = 158564
157 + 158407 = 158564
193 + 158371 = 158564
223 + 158341 = 158564
271 + 158293 = 158564
331 + 158233 = 158564
337 + 158227 = 158564

Showing the first eight; more decompositions exist.
