Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462920, here are decompositions:
- 11 + 31462909 = 31462920
- 19 + 31462901 = 31462920
- 23 + 31462897 = 31462920
- 31 + 31462889 = 31462920
- 43 + 31462877 = 31462920
- 89 + 31462831 = 31462920
- 109 + 31462811 = 31462920
- 113 + 31462807 = 31462920
Showing the first eight; more decompositions exist.
