Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101140, here are decompositions:

23 + 101117 = 101140
29 + 101111 = 101140
59 + 101081 = 101140
89 + 101051 = 101140
113 + 101027 = 101140
131 + 101009 = 101140
197 + 100943 = 101140
227 + 100913 = 101140

Showing the first eight; more decompositions exist.
