Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461316, here are decompositions:
- 23 + 31461293 = 31461316
- 137 + 31461179 = 31461316
- 167 + 31461149 = 31461316
- 269 + 31461047 = 31461316
- 389 + 31460927 = 31461316
- 443 + 31460873 = 31461316
- 479 + 31460837 = 31461316
- 587 + 31460729 = 31461316
Showing the first eight; more decompositions exist.
