Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528524, here are decompositions:
- 23 + 31528501 = 31528524
- 73 + 31528451 = 31528524
- 151 + 31528373 = 31528524
- 197 + 31528327 = 31528524
- 211 + 31528313 = 31528524
- 233 + 31528291 = 31528524
- 241 + 31528283 = 31528524
- 257 + 31528267 = 31528524
Showing the first eight; more decompositions exist.
