Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99770, here are decompositions:
- 3 + 99767 = 99770
- 37 + 99733 = 99770
- 61 + 99709 = 99770
- 103 + 99667 = 99770
- 109 + 99661 = 99770
- 127 + 99643 = 99770
- 163 + 99607 = 99770
- 193 + 99577 = 99770
Showing the first eight; more decompositions exist.
