Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526772, here are decompositions:
- 19 + 31526753 = 31526772
- 23 + 31526749 = 31526772
- 41 + 31526731 = 31526772
- 59 + 31526713 = 31526772
- 83 + 31526689 = 31526772
- 103 + 31526669 = 31526772
- 139 + 31526633 = 31526772
- 239 + 31526533 = 31526772
Showing the first eight; more decompositions exist.
