Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527776, here are decompositions:
- 67 + 31527709 = 31527776
- 73 + 31527703 = 31527776
- 79 + 31527697 = 31527776
- 193 + 31527583 = 31527776
- 199 + 31527577 = 31527776
- 277 + 31527499 = 31527776
- 433 + 31527343 = 31527776
- 499 + 31527277 = 31527776
Showing the first eight; more decompositions exist.
