Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528484, here are decompositions:
- 37 + 31528447 = 31528484
- 157 + 31528327 = 31528484
- 193 + 31528291 = 31528484
- 271 + 31528213 = 31528484
- 277 + 31528207 = 31528484
- 313 + 31528171 = 31528484
- 373 + 31528111 = 31528484
- 487 + 31527997 = 31528484
Showing the first eight; more decompositions exist.
