Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69820, here are decompositions:
- 11 + 69809 = 69820
- 41 + 69779 = 69820
- 53 + 69767 = 69820
- 59 + 69761 = 69820
- 83 + 69737 = 69820
- 167 + 69653 = 69820
- 197 + 69623 = 69820
- 227 + 69593 = 69820
Showing the first eight; more decompositions exist.
