Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80670, here are decompositions:
- 13 + 80657 = 80670
- 19 + 80651 = 80670
- 41 + 80629 = 80670
- 43 + 80627 = 80670
- 59 + 80611 = 80670
- 67 + 80603 = 80670
- 71 + 80599 = 80670
- 103 + 80567 = 80670
Showing the first eight; more decompositions exist.
