Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543132, here are decompositions:
- 29 + 31543103 = 31543132
- 53 + 31543079 = 31543132
- 113 + 31543019 = 31543132
- 191 + 31542941 = 31543132
- 251 + 31542881 = 31543132
- 653 + 31542479 = 31543132
- 773 + 31542359 = 31543132
- 809 + 31542323 = 31543132
Showing the first eight; more decompositions exist.
