Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153558, here are decompositions:

29 + 153529 = 153558
37 + 153521 = 153558
47 + 153511 = 153558
59 + 153499 = 153558
71 + 153487 = 153558
89 + 153469 = 153558
101 + 153457 = 153558
109 + 153449 = 153558

Showing the first eight; more decompositions exist.
