Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57212, here are decompositions:

19 + 57193 = 57212
73 + 57139 = 57212
139 + 57073 = 57212
223 + 56989 = 57212
229 + 56983 = 57212
271 + 56941 = 57212
283 + 56929 = 57212
433 + 56779 = 57212

Showing the first eight; more decompositions exist.
