Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543024, here are decompositions:
- 5 + 31543019 = 31543024
- 53 + 31542971 = 31543024
- 83 + 31542941 = 31543024
- 113 + 31542911 = 31543024
- 167 + 31542857 = 31543024
- 197 + 31542827 = 31543024
- 257 + 31542767 = 31543024
- 347 + 31542677 = 31543024
Showing the first eight; more decompositions exist.
