Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539464, here are decompositions:
- 43 + 31539421 = 31539464
- 97 + 31539367 = 31539464
- 127 + 31539337 = 31539464
- 181 + 31539283 = 31539464
- 193 + 31539271 = 31539464
- 223 + 31539241 = 31539464
- 421 + 31539043 = 31539464
- 457 + 31539007 = 31539464
Showing the first eight; more decompositions exist.
