Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587016, here are decompositions:
- 89 + 31586927 = 31587016
- 113 + 31586903 = 31587016
- 137 + 31586879 = 31587016
- 317 + 31586699 = 31587016
- 347 + 31586669 = 31587016
- 389 + 31586627 = 31587016
- 479 + 31586537 = 31587016
- 569 + 31586447 = 31587016
Showing the first eight; more decompositions exist.
