Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544080, here are decompositions:
- 3 + 31544077 = 31544080
- 23 + 31544057 = 31544080
- 41 + 31544039 = 31544080
- 47 + 31544033 = 31544080
- 59 + 31544021 = 31544080
- 83 + 31543997 = 31544080
- 89 + 31543991 = 31544080
- 101 + 31543979 = 31544080
Showing the first eight; more decompositions exist.
