Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42684, here are decompositions:
- 7 + 42677 = 42684
- 17 + 42667 = 42684
- 41 + 42643 = 42684
- 43 + 42641 = 42684
- 73 + 42611 = 42684
- 107 + 42577 = 42684
- 113 + 42571 = 42684
- 127 + 42557 = 42684
Showing the first eight; more decompositions exist.
