Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497862, here are decompositions:
- 3 + 31497859 = 31497862
- 59 + 31497803 = 31497862
- 89 + 31497773 = 31497862
- 191 + 31497671 = 31497862
- 293 + 31497569 = 31497862
- 311 + 31497551 = 31497862
- 401 + 31497461 = 31497862
- 419 + 31497443 = 31497862
Showing the first eight; more decompositions exist.
