Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152858, here are decompositions:

7 + 152851 = 152858
19 + 152839 = 152858
37 + 152821 = 152858
67 + 152791 = 152858
229 + 152629 = 152858
241 + 152617 = 152858
397 + 152461 = 152858
439 + 152419 = 152858

Showing the first eight; more decompositions exist.
