Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28254, here are decompositions:
- 43 + 28211 = 28254
- 53 + 28201 = 28254
- 71 + 28183 = 28254
- 73 + 28181 = 28254
- 103 + 28151 = 28254
- 131 + 28123 = 28254
- 157 + 28097 = 28254
- 167 + 28087 = 28254
Showing the first eight; more decompositions exist.
