Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562, here are decompositions:
- 19 + 31543 = 31562
- 31 + 31531 = 31562
- 73 + 31489 = 31562
- 229 + 31333 = 31562
- 241 + 31321 = 31562
- 313 + 31249 = 31562
- 331 + 31231 = 31562
- 373 + 31189 = 31562
Showing the first eight; more decompositions exist.
