Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85180, here are decompositions:

47 + 85133 = 85180
59 + 85121 = 85180
71 + 85109 = 85180
89 + 85091 = 85180
131 + 85049 = 85180
233 + 84947 = 85180
311 + 84869 = 85180
353 + 84827 = 85180

Showing the first eight; more decompositions exist.
