Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42558, here are decompositions:

59 + 42499 = 42558
67 + 42491 = 42558
71 + 42487 = 42558
97 + 42461 = 42558
101 + 42457 = 42558
107 + 42451 = 42558
149 + 42409 = 42558
151 + 42407 = 42558

Showing the first eight; more decompositions exist.
