Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42680, here are decompositions:

3 + 42677 = 42680
13 + 42667 = 42680
31 + 42649 = 42680
37 + 42643 = 42680
103 + 42577 = 42680
109 + 42571 = 42680
181 + 42499 = 42680
193 + 42487 = 42680

Showing the first eight; more decompositions exist.
