Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29512, here are decompositions:
- 11 + 29501 = 29512
- 29 + 29483 = 29512
- 59 + 29453 = 29512
- 83 + 29429 = 29512
- 89 + 29423 = 29512
- 101 + 29411 = 29512
- 113 + 29399 = 29512
- 149 + 29363 = 29512
Showing the first eight; more decompositions exist.
