Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542432, here are decompositions:
- 13 + 31542419 = 31542432
- 41 + 31542391 = 31542432
- 59 + 31542373 = 31542432
- 73 + 31542359 = 31542432
- 109 + 31542323 = 31542432
- 151 + 31542281 = 31542432
- 199 + 31542233 = 31542432
- 269 + 31542163 = 31542432
Showing the first eight; more decompositions exist.
