Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80740, here are decompositions:
- 3 + 80737 = 80740
- 53 + 80687 = 80740
- 59 + 80681 = 80740
- 71 + 80669 = 80740
- 83 + 80657 = 80740
- 89 + 80651 = 80740
- 113 + 80627 = 80740
- 137 + 80603 = 80740
Showing the first eight; more decompositions exist.
