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.
