Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527296, here are decompositions:
- 19 + 31527277 = 31527296
- 43 + 31527253 = 31527296
- 103 + 31527193 = 31527296
- 139 + 31527157 = 31527296
- 397 + 31526899 = 31527296
- 433 + 31526863 = 31527296
- 487 + 31526809 = 31527296
- 523 + 31526773 = 31527296
Showing the first eight; more decompositions exist.
