Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29172, here are decompositions:
- 5 + 29167 = 29172
- 19 + 29153 = 29172
- 41 + 29131 = 29172
- 43 + 29129 = 29172
- 71 + 29101 = 29172
- 109 + 29063 = 29172
- 113 + 29059 = 29172
- 139 + 29033 = 29172
Showing the first eight; more decompositions exist.
