Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84820, here are decompositions:
- 11 + 84809 = 84820
- 59 + 84761 = 84820
- 83 + 84737 = 84820
- 89 + 84731 = 84820
- 101 + 84719 = 84820
- 107 + 84713 = 84820
- 167 + 84653 = 84820
- 191 + 84629 = 84820
Showing the first eight; more decompositions exist.
