Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542706, here are decompositions:
- 3 + 31542703 = 31542706
- 29 + 31542677 = 31542706
- 47 + 31542659 = 31542706
- 197 + 31542509 = 31542706
- 227 + 31542479 = 31542706
- 269 + 31542437 = 31542706
- 347 + 31542359 = 31542706
- 383 + 31542323 = 31542706
Showing the first eight; more decompositions exist.
