Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544538, here are decompositions:
- 5 + 31544533 = 31544538
- 7 + 31544531 = 31544538
- 29 + 31544509 = 31544538
- 167 + 31544371 = 31544538
- 191 + 31544347 = 31544538
- 227 + 31544311 = 31544538
- 241 + 31544297 = 31544538
- 257 + 31544281 = 31544538
Showing the first eight; more decompositions exist.
