Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471846, here are decompositions:
- 23 + 31471823 = 31471846
- 47 + 31471799 = 31471846
- 59 + 31471787 = 31471846
- 83 + 31471763 = 31471846
- 149 + 31471697 = 31471846
- 179 + 31471667 = 31471846
- 269 + 31471577 = 31471846
- 389 + 31471457 = 31471846
Showing the first eight; more decompositions exist.
