Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517932, here are decompositions:
- 23 + 31517909 = 31517932
- 53 + 31517879 = 31517932
- 71 + 31517861 = 31517932
- 233 + 31517699 = 31517932
- 293 + 31517639 = 31517932
- 353 + 31517579 = 31517932
- 359 + 31517573 = 31517932
- 389 + 31517543 = 31517932
Showing the first eight; more decompositions exist.
