Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20702, here are decompositions:
- 61 + 20641 = 20702
- 103 + 20599 = 20702
- 109 + 20593 = 20702
- 139 + 20563 = 20702
- 151 + 20551 = 20702
- 181 + 20521 = 20702
- 193 + 20509 = 20702
- 223 + 20479 = 20702
Showing the first eight; more decompositions exist.
