Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20670, here are decompositions:
- 7 + 20663 = 20670
- 29 + 20641 = 20670
- 31 + 20639 = 20670
- 43 + 20627 = 20670
- 59 + 20611 = 20670
- 71 + 20599 = 20670
- 107 + 20563 = 20670
- 127 + 20543 = 20670
Showing the first eight; more decompositions exist.
