Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82240, here are decompositions:

3 + 82237 = 82240
17 + 82223 = 82240
23 + 82217 = 82240
47 + 82193 = 82240
101 + 82139 = 82240
167 + 82073 = 82240
173 + 82067 = 82240
227 + 82013 = 82240

Showing the first eight; more decompositions exist.
