Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57158, here are decompositions:

19 + 57139 = 57158
61 + 57097 = 57158
229 + 56929 = 57158
331 + 56827 = 57158
337 + 56821 = 57158
349 + 56809 = 57158
379 + 56779 = 57158
421 + 56737 = 57158

Showing the first eight; more decompositions exist.
