Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541592, here are decompositions:
- 11 + 31541581 = 31541592
- 23 + 31541569 = 31541592
- 29 + 31541563 = 31541592
- 83 + 31541509 = 31541592
- 109 + 31541483 = 31541592
- 163 + 31541429 = 31541592
- 191 + 31541401 = 31541592
- 193 + 31541399 = 31541592
Showing the first eight; more decompositions exist.
