Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533576, here are decompositions:
- 5 + 31533571 = 31533576
- 13 + 31533563 = 31533576
- 29 + 31533547 = 31533576
- 43 + 31533533 = 31533576
- 59 + 31533517 = 31533576
- 79 + 31533497 = 31533576
- 127 + 31533449 = 31533576
- 163 + 31533413 = 31533576
Showing the first eight; more decompositions exist.
