Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20694, here are decompositions:
- 13 + 20681 = 20694
- 31 + 20663 = 20694
- 53 + 20641 = 20694
- 67 + 20627 = 20694
- 83 + 20611 = 20694
- 101 + 20593 = 20694
- 131 + 20563 = 20694
- 151 + 20543 = 20694
Showing the first eight; more decompositions exist.
