Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42582, here are decompositions:

5 + 42577 = 42582
11 + 42571 = 42582
13 + 42569 = 42582
73 + 42509 = 42582
83 + 42499 = 42582
109 + 42473 = 42582
131 + 42451 = 42582
139 + 42443 = 42582

Showing the first eight; more decompositions exist.
