Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80870, here are decompositions:
- 7 + 80863 = 80870
- 37 + 80833 = 80870
- 61 + 80809 = 80870
- 67 + 80803 = 80870
- 109 + 80761 = 80870
- 157 + 80713 = 80870
- 193 + 80677 = 80870
- 199 + 80671 = 80870
Showing the first eight; more decompositions exist.
