Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28212, here are decompositions:
- 11 + 28201 = 28212
- 29 + 28183 = 28212
- 31 + 28181 = 28212
- 61 + 28151 = 28212
- 89 + 28123 = 28212
- 101 + 28111 = 28212
- 103 + 28109 = 28212
- 113 + 28099 = 28212
Showing the first eight; more decompositions exist.
