Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532718, here are decompositions:
- 31 + 31532687 = 31532718
- 59 + 31532659 = 31532718
- 79 + 31532639 = 31532718
- 131 + 31532587 = 31532718
- 137 + 31532581 = 31532718
- 167 + 31532551 = 31532718
- 179 + 31532539 = 31532718
- 197 + 31532521 = 31532718
Showing the first eight; more decompositions exist.
