Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83740, here are decompositions:

3 + 83737 = 83740
23 + 83717 = 83740
101 + 83639 = 83740
131 + 83609 = 83740
149 + 83591 = 83740
179 + 83561 = 83740
263 + 83477 = 83740
269 + 83471 = 83740

Showing the first eight; more decompositions exist.
