Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527910, here are decompositions:
- 23 + 31527887 = 31527910
- 83 + 31527827 = 31527910
- 233 + 31527677 = 31527910
- 251 + 31527659 = 31527910
- 389 + 31527521 = 31527910
- 419 + 31527491 = 31527910
- 503 + 31527407 = 31527910
- 521 + 31527389 = 31527910
Showing the first eight; more decompositions exist.
