Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544186, here are decompositions:
- 7 + 31544179 = 31544186
- 19 + 31544167 = 31544186
- 97 + 31544089 = 31544186
- 109 + 31544077 = 31544186
- 199 + 31543987 = 31544186
- 283 + 31543903 = 31544186
- 313 + 31543873 = 31544186
- 409 + 31543777 = 31544186
Showing the first eight; more decompositions exist.
