Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83540, here are decompositions:

3 + 83537 = 83540
43 + 83497 = 83540
97 + 83443 = 83540
103 + 83437 = 83540
109 + 83431 = 83540
139 + 83401 = 83540
151 + 83389 = 83540
157 + 83383 = 83540

Showing the first eight; more decompositions exist.
