Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80730, here are decompositions:
- 17 + 80713 = 80730
- 29 + 80701 = 80730
- 43 + 80687 = 80730
- 47 + 80683 = 80730
- 53 + 80677 = 80730
- 59 + 80671 = 80730
- 61 + 80669 = 80730
- 73 + 80657 = 80730
Showing the first eight; more decompositions exist.
