Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528364, here are decompositions:
- 37 + 31528327 = 31528364
- 73 + 31528291 = 31528364
- 97 + 31528267 = 31528364
- 151 + 31528213 = 31528364
- 157 + 31528207 = 31528364
- 193 + 31528171 = 31528364
- 271 + 31528093 = 31528364
- 367 + 31527997 = 31528364
Showing the first eight; more decompositions exist.
