Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80742, here are decompositions:
- 5 + 80737 = 80742
- 29 + 80713 = 80742
- 41 + 80701 = 80742
- 59 + 80683 = 80742
- 61 + 80681 = 80742
- 71 + 80671 = 80742
- 73 + 80669 = 80742
- 113 + 80629 = 80742
Showing the first eight; more decompositions exist.
