Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531002, here are decompositions:
- 23 + 31530979 = 31531002
- 29 + 31530973 = 31531002
- 43 + 31530959 = 31531002
- 59 + 31530943 = 31531002
- 101 + 31530901 = 31531002
- 109 + 31530893 = 31531002
- 229 + 31530773 = 31531002
- 353 + 31530649 = 31531002
Showing the first eight; more decompositions exist.
