Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532706, here are decompositions:
- 13 + 31532693 = 31532706
- 19 + 31532687 = 31532706
- 47 + 31532659 = 31532706
- 53 + 31532653 = 31532706
- 67 + 31532639 = 31532706
- 109 + 31532597 = 31532706
- 113 + 31532593 = 31532706
- 167 + 31532539 = 31532706
Showing the first eight; more decompositions exist.
