Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528402, here are decompositions:
- 29 + 31528373 = 31528402
- 53 + 31528349 = 31528402
- 89 + 31528313 = 31528402
- 173 + 31528229 = 31528402
- 233 + 31528169 = 31528402
- 251 + 31528151 = 31528402
- 281 + 31528121 = 31528402
- 383 + 31528019 = 31528402
Showing the first eight; more decompositions exist.
