Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84140, here are decompositions:

3 + 84137 = 84140
13 + 84127 = 84140
19 + 84121 = 84140
73 + 84067 = 84140
79 + 84061 = 84140
157 + 83983 = 84140
229 + 83911 = 84140
271 + 83869 = 84140

Showing the first eight; more decompositions exist.
