Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586626, here are decompositions:
- 47 + 31586579 = 31586626
- 83 + 31586543 = 31586626
- 89 + 31586537 = 31586626
- 179 + 31586447 = 31586626
- 353 + 31586273 = 31586626
- 389 + 31586237 = 31586626
- 479 + 31586147 = 31586626
- 569 + 31586057 = 31586626
Showing the first eight; more decompositions exist.
