Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70820, here are decompositions:
- 37 + 70783 = 70820
- 67 + 70753 = 70820
- 103 + 70717 = 70820
- 157 + 70663 = 70820
- 163 + 70657 = 70820
- 181 + 70639 = 70820
- 193 + 70627 = 70820
- 199 + 70621 = 70820
Showing the first eight; more decompositions exist.
