Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540206, here are decompositions:
- 17 + 31540189 = 31540206
- 43 + 31540163 = 31540206
- 59 + 31540147 = 31540206
- 83 + 31540123 = 31540206
- 97 + 31540109 = 31540206
- 107 + 31540099 = 31540206
- 193 + 31540013 = 31540206
- 197 + 31540009 = 31540206
Showing the first eight; more decompositions exist.
