Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27156, here are decompositions:
- 13 + 27143 = 27156
- 29 + 27127 = 27156
- 47 + 27109 = 27156
- 53 + 27103 = 27156
- 79 + 27077 = 27156
- 83 + 27073 = 27156
- 89 + 27067 = 27156
- 97 + 27059 = 27156
Showing the first eight; more decompositions exist.
