Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543162, here are decompositions:
- 29 + 31543133 = 31543162
- 59 + 31543103 = 31543162
- 83 + 31543079 = 31543162
- 191 + 31542971 = 31543162
- 251 + 31542911 = 31543162
- 281 + 31542881 = 31543162
- 353 + 31542809 = 31543162
- 503 + 31542659 = 31543162
Showing the first eight; more decompositions exist.
